Onyx Coffee Lab

Had an iced vanilla latte. Was amazing. I waited two years for this. Every year I’ve stayed in Bentonville I haven’t made the time to wait for the coffee. This place is always packed especially in the mornings. Was able to get there in the afternoon on a Saturday and there were about a dozen people in line. Is a great spot to hang out and do remote work. Definitely in my top 10 coffee places all time in the country. You need to stop here if you can!

Great coffee shop! The coffee tasted great and there is obvious quality in every cup. I got the iced salted mocha. The line was quite long on a Sunday morning, it was about a 15 minute wait. Glad we tried it out!

We came for coffee bright and early on Friday morning around 7am. There was no line but there were already several people and groups posted up in the seating area. I had the Costa Rican single origin pour over coffee and my husband got the terroir hat trick. Service was friendly and our order came out quickly. We didn’t get any food but they had a decent selection of pastries and sweets available. Good coffee, good vibes.

Onyx Coffee Lab in downtown is a standout destination for coffee lovers. Known for its high-quality beans and precision brewing, it offers an exceptional experience for both casual drinkers and connoisseurs alike. The ambiance is modern and inviting, with a sleek yet cozy design that blends seamlessly with Bentonville’s vibrant downtown vibe. Their menu is thoughtfully curated, offering a range of espresso drinks, pour-overs, and signature blends. Each cup is crafted with care, highlighting the distinct flavors of their ethically sourced beans. The baristas are knowledgeable and passionate, always willing to share recommendations or explain the nuances of their beans. We got pistachio macarons and a hazelnut chocolate flavored latte and loved both. Whether you’re in the mood for a classic latte or something more adventurous like a nitro cold brew, Onyx delivers on taste and quality. The staff is friendly and welcoming, and the café itself is a great spot to relax or work, with ample seating and a lively, community-focused atmosphere. Onyx also supports local events and partnerships, contributing to the town’s growing culinary culture.

Came on a Sunday afternoon and they were packed, but the line was quick, staff was super friendly, and coffee was good and came out quickly. Came back on Monday and had another excellent experience! Super good coffee! We tried the Pistachio Matcha, Onyx Delight, hail Mary something, and the salt mocha. All were delicious. About $6 a drink so fun for a treat on vacation

Onyx offers an incredible vibe, perfect for relaxing or catching up with friends. The ambiance is cozy and welcoming, with stylish decor. The coffee is top-notch, rich in flavor and brewed to perfection, making it the ideal spot for any coffee lover. Whether you’re working or unwinding, this place provides the perfect balance of comfort and quality. Highly recommend!

I came for a good cup of coffee. I ordered the light roast, and it tasted like a watered-down Americano. I was very disappointed. The food must be good, given that people were waiting in a long line to order. I ended up throwing the coffee out, It was a 5 buck cup of coffee. I don't think I'd go back for coffee.

Great vibe and a nice place to hang out with friends or enjoy some quiet time alone. The coffee was decent, but the standout for me was the salted caramel mocha—absolutely delicious! Overall, a pleasant experience.

This place was super busy and all that seemed justified. Everything on the menu looked and sounded really good. I saw other people with breakfast sandwiches that looked amazing, but I didn't see those until after I ordered. I can only speak to the coffee. Since it was still kind of warm outside I asked for an iced black coffee. The guy taking my order recommended a nitro iced black coffee, so I went with that. It was a great rec because I really enjoyed that coffee. We sat outside in front. It was a great spot to enjoy the early fall weather. I definitely plan to come back on my next visit to Bentonville.

Was visiting the area from CA on vacation and was ASTONISHED at the architecture and design of this building place! It seriously deserves to be in architectural digest. Overall I liked the selection of coffees and pastries but unfortunately did find the espresso a little weak....I got a flat white and even then it had a milky taste - not the strongest pull. Service was professional, there was a long line (15 min?) wrapping all around the bar but it gave me time to admire all the little interior design wonders. As a certified coffee snob this was a haven from big chain drive drive throughs and in such a cute little area of town!

Service was outstanding. Everyone was super helpful! Coffee selection was a decent spread, but food options are pretty limited. It's not really brunch but they do have pastries. Very vibey- if I was in college I would definitely spend a decent amount of time hanging out here. I will be back!

Vibe was cool and service was really good. All the food was really good too! My favorite thing was the onigiri. We got a bacon and egg, but they also have lunch options with other meats in them. It was just a really unique thing for a coffee shop to have. Coffee good and they have a lot of options for non coffee drinkers too.

I visited Onyx in downtown on a Saturday during the farmers market. It was very busy. The service was fast and the baristas were very kind. I ordered the Onyx Delight iced. It was sweet but I could still taste the espresso shine through. Pro tip: request that they use Monarch espresso instead of their normal Geometry espresso for any latte!

We came for coffee bright and early on Friday morning around 7am. There was no line but there were already several people and groups posted up in the seating area. I had the Costa Rican single origin pour over coffee and my husband got the terroir hat trick. Service was friendly and our order came out quickly. We didn't get any food but they had a decent selection of pastries and sweets available. Good coffee, good vibes.

Very cute coffee shop! Had one the best lattes I've had in a while Chocolate Cream Croissant (3.5/5) - ehh Hail Fellow Well Met Latte (4.5/5) - if you're into a brown butter flavor this is the one! It was very creamy from the oat milk :) and a little too sweet for my liking but it was probably because I got it with light ice.

A super trendy coffee shop with long lines. We went on a Saturday and it was packed! There were a lot of options on the menu that I was really drawn to, and in the end I opted to get the Hail Fellow Well Met, because it had browned butter as an ingredient and I had never seen that in a latte before. It ended up being one of the best lattes I've ever had, with such a unique flavor. Their seasonal flavors sounded inventive and delicious as well. I wish I had Onyx Coffee Lab back home, because the Hail Fellow was that good. There's enough seating here that even with the large crowd, we found a place to sit pretty easily. And despite the long lines, the drinks were ready pretty shortly after ordering.

Came here on a Thurs morning to fuel up for a day of mountain biking. their avocado toast was delicious as were their chocolate croissants. the house coffee was great too. i really enjoyed sitting outside and seeing all the people on a Thursday enjoying this coffee shop. we had a great experience from ordering to getting our food. highly recommend.

First time trying Onyx. Best friend took me here and service was great! We ordered pastries along with the food and drinks we ordered. Everything tasted so good and the blue botanical shake was the perfect blend of all their ingredients. We went out to try the coffee from the robot outside and it was pretty good! The ambiance is mixed - you have big groups meeting along with individuals that sit at their bar doing work. A little pricey but worth it!

Pretty sure it's the best coffee shop in town, since I've tried a few by now. Always a line, and it's for a good reason. Service is fast - they have it down to a science. They use high quality beans and machines to produce exceptional lattes. They also have unique ones that taste delicious. It has an upscale and hip ambience. You definitely feel like you're 'at the spot.'

Overall good coffee. Long lines so not worth coming if you have to head into work right after. Once you order you receive your coffee pretty quick. The tops of the coffee cups are weird, hard to drink the coffee with it.

We walked from our hotel to get breakfast and coffee and are so glad we did. It was busy when we arrived, but the line moved fast and the service was friendly and helpful. The avocado toast was tasty and the bread nicely crunchy and not soggy. My husband had the sticky bun which was flavorful but not exactly sticky. It had a dry texture with moderate sweetness. We both had the house coffee, and I always love it when they use glass mugs for "here" orders. Good vibe and great coffee.

Onyx has incredible coffee, content, and great merch. Tons of variety that is seasonal and ever changing. The negative though is in their customer service, consistently consumed their coffee and will continue to follow and support their content but won't be making future purchases. I had spent nearly $200 on products that were lost in the mail. When i reached out, one of the items was no longer in stock. Talking with their customer service was a major pain point. First the communication was very inconsistent. Then they asked if i would like a $10 discount which didn't even cover the tax on my order and they were very specific that it was a one time only offer only as if i was trying to rip them off or something. Alternatively, they said they could issue a full refund. I replied that i would take a full refund and they responded that they had already went ahead and re-shipped the item with the $10 discount but not to worry, i could return it all. Again, putting the hassle on me rather than reading my response. Great products but piss poor customer service, they simply don't care about their customers, all they care about is making their sales and collecting their profits. Highly disappointed.

Went here this past weekend after seeing a review that said that this was the BEST coffee experience that the reviewer had ever had. We put the address into the GPS and we were on our way. The inside looks really cool and expensive. There's a neat neon sign. There are cool modern tables, a pretty, penny tiled bar and various types of seating for getting work done or chatting. There is also additional outdoor seating. I was part of a party of four and after looking over the menu, two of them declined to order anything. We purchased two drinks to go, one hot, one iced. My husband got a flat white. He's had flat whites everywhere, including New Zealand so he knows what they taste like. He said his drink was tasteless. Perhaps it was a watery shot? Prior to ordering I told the cashier that I have celiac and was wondering if they knew if their salt mocha was gluten-free. The cashier asked someone pulling shots, and then said, "ahh I'm pretty sure it is." It was already after 3 PM and all I'd had the entire day was a cookie and a scone from down the street. I shouldn't have trusted it, but I went ahead with my order. What came out was a drink that tasted like chocolate milk. I was about a third of the way through it when my stomach started to hurt, so I told my non-celiac family member to finish the drink. They also said it tasted like chocolate milk. Did it contain gluten? Not sure. Possible cross-contamination issues perhaps? Be warned, while it is disclosed on the lower corner of the menu, they have one of those junk fees tacked on for employee benefits. Labor costs are the cost of doing business and should be calculated into the menu price (which is exactly why Sacramento, California is outlawing these junk fees.) "Businesses use hidden fees or junk fees to pitch an artificially low headline price to attract a customer before revealing additional charges," - Eleanor Blume, California's assistant attorney general. Don't have an artificially lower price to entice customers and then have the real cost come out at the register. Have all your labor costs, rent, ingredients, profit margins all factored into your advertised menu price and then have separate line items for each type of tax being charged. Being transparent with customers about pricing is not rocket science. Would I agree with the poster that this was the best coffee experience I've ever had? No. Was it offensively bad where it warrants a 1 star? No. Visited April 2024

If you can get over the line, everything is worth the wait. Pastries, coffee, matcha. Couldn't ask for better food. And the design

This is for their online coffee biz: Quality coffee offerings but bogged down by Snail like delivery service and same with inquiries - orders and responses take looonnngg time to show up. They always blame it on something when I do get a response .Other online vendors outperform onyx time and time again I still haven't learned my lesson as I'm currently waiting for an order placed on Nov 29 THAT HASN'T EVEN SHIPPED YET. I am an online seller and I couldn't get away with this. Obviously their brick n mortar stores are the priority. Did I say never again

This place has an amazing menu and the staff is awesome! Their seasonal menu was exactly what I needed! I ordered one of their seasonal lattes and was so happy with my choice! The flavor was spot on! Then I got the avocado toast and that was good too! I also really liked that they had private rooms that we could book to bring in a team to work together. The room was large and was really clean! Great space and good menu!

Great coffee and experience. Really cool vibe with plenty of seating and good amount of options on the menu. Looking forward to stopping here when I'm in the area.

6/14/23 ONYX COFFEEE LAB - Where have you been all my life for trips to Bentonville?!? A coworker recommended Onyx as a great stop for coffee and he did not lie! I ordered the FOMO and could have had 2 more! It was a tad high at $6.50 cup but yummm. Almond croissants are $5.75/each and the lemon poppyseed hibiscus muffin was $4.25. I had 1/3 of the muffin and didn't care for the rest. Served warm, but taste was just not for me. Coworker enjoyed the almond croissant very much - he had 2! Coworker had a cappuccino - $4 and it came with a side of sparkling water. It's a unique and vibing coffee lab place to check out. Staff was friendly. Decor is very modern. I can't recall the last time grabbing coffee was $40 (after tip) but I'd definitely come back!

I heard about this place before even coming to Bentonville so I made it a point to stop in while we were in town. The coffee was good and lattes were perfect. I had the onyx delight and my friend had the salt mocha. I liked both. The inside is very posh and upscale decor but it still had the cozy coffee house vibes. The staff were friendly and efficient. The line wrapped around the bar but everyone got their coffee shortly after ordering. Plenty of seating inside and outside on the sidewalk. We enjoyed watching all the dogs on the patio. I recommend stopping in to Onyx when you're in Arkansas.

Beautiful setting and the salted mocha is just divine! The staff are all super friendly!

Definitely worth the trip to this coffee shop. There may be a long line but staff are super efficient and quick. The environment is very welcoming and there's lots of open seating. Their coffee is super smooth and delicious. Check out their merch when you're here.

I was recommended Onyx from a friend and it is LITERALLY my favorite coffee place I've ever been to! Their coffee is so smooth and it's the perfect taste for me. Ambiance was great and service fast. I went and studied for a few hours and was surprised at the amount of people visiting for a Tuesday at 10 am. Staff were professional and seemed like they genuinely enjoyed their jobs! I'm from Kansas City and was THRILLED to learn that Vested Coffee in KC serves Onyx Coffee!!

This is a beautiful space, they serve fantastic coffee, however their ventilation system when they are cooking breakfast needs some help. The whole place smells like paninis. Not such a bad thing until you leave and your clothes, hair, etc all smell like food all day. The service is always good, employees are friendly. I would always recommend someone to go here. Great place to chill, work, visit with a friend, whatever; just be warned that it gets VERY busy. Like line wrapped around the bar, lucky to find a seat busy.

Overall score 4.7 out of 5 I've been here a few times now the coffee and Matcha is very good. Usually Matcha is very hard to get right, so I was very pleased. This place was able to do it. Even the breakfast sandwich was pretty great. Staff and location is great. I would go again

I was so pleased to learn that the Onyx coffee I have been enjoying in LA for years originates here in Arkansas. The variety of drinks is great, and this place checks all the oaky boxes for a work-friendly but creative ambience. I also appreciate how clean it is--this whole town is pretty clean. I only dock a star because there are some pretty serious air vents above a lot of the seating, it gets very cold. There are also standing tables that lack seating. This could be a good thing for them, as it keeps people moving, but as I tend to rate coffeeshops based on how hospitable they are for long, writerly sits, it's a con for me personally.

Overall experience was truly "meh." Onyx Coffee Lab is such a beloved spot in Bentonville, but I just wasn't impressed. I visited Onyx on a Sunday afternoon with two friends. It was not my first time visiting the coffee shop, and I will say, I've had better experiences there but nothing out-of-this-world. In the past, the Onyx has been very busy, with a line wrapping around much of the center coffee bar. Fortunately upon my most recent visit, we didn't have to wait in line at all. I'm assuming this is because my former visits were during the summer and fall and my most recent visit was during the dead of winter. I ordered an iced chai latte and a chocolate tart. Both are forgettable and were pricey for the quality. As a chai latte fan, I enjoyed the spice level of the drink but it just tasted watered down to me. My cup was also full of so much ice. I felt like I didn't have that much to drink. The tart was fine. Nothing I will remember or talk about (unless it's telling people to not waste $3.50 on a chocolate tart that is about 1-inch in diameter). My total was about $10. The staff were very pleasant (and have been in the past). They genuinely seem to care about the customers, no matter how busy they are. I enjoy and appreciate that! The atmosphere of Onyx is very cool and I understand why so many people enjoy it as a spot to hangout. But if you're just looking to swing in a coffee shop (especially if you're not a coffee drinker like me) than I'd suggest going elsewhere.

Delicious local coffee with a variety of options. I got one of their seasonal drinks and my husband got a drip. The shop has a lot of seating. Customer service was friendly. Definitely recommend to visit for your next cup of coffee.

A little sweet taste of heaven! I love their unique menu for drinks. So much that I would love to try each of it but since we only have a little time here in Bentonville I tried their matcha latte. It was perfect for a cold rainy day. We were strolling around downtown and it kept me warm and really just happy. It was creamy, smooth, sweet and the matcha tea tasted like I never ever tasted before. It was soo good that I got angry at my husband that he didn't order me a large but a small cup! The interior is very modern, clean with many seating option for people to work with their laptop or just to hang out for a quick coffee with friends. It's bright and they also have very cute outdoor seatings. I wish they would have this exact coffee place somewhere in Dallas Texas. This is just pure joy for your eyes from interior to drinks and your tastebuds. Absolutely stunning! 5 stars! Bentonville I'm jealous that you have this amazing coffee shop!

The iced Hail Fellow Well Met Latte is a lovely caramel drink in a summer's day. The macarons are fun to sample as well- we got strawberry champagne, and cookies and cream.

Great atmosphere, great food and great coffee. A perfect hang out area. Nice service.

Pricing. Charging $30 for a 10 ounce bag of coffee is beyond pretentious. Go elsewhere.

Great coffee shop in downtown Bentonville. Great staff as well. Even when busy drinks come out at. Good pace.

Onyx Coffee Lab is a gem in every sense! From the moment you step in, you're greeted with the irresistible aroma of freshly brewed coffee. The treats here are absolutely delicious - each bite is a taste of perfection! Whether you're a coffee aficionado or just looking for a cozy spot to enjoy a cup, Onyx is the place to be. The staff is friendly and knowledgeable, making the whole experience even better. Don't miss out on their incredible coffee beverages and treats - a must-visit spot for any coffee lover! #OnyxCoffeeLab #CoffeeLoversParadise #DeliciousTreats

Great vibes here. Informative, if you have questions regarding roasts and profile characteristics.

After sampling their product at Vested Coffee in Kansas City and seeing Onyx on a few 'Best of' lists, I bookmarked them and finally got to visit in person at their downtown Bentonville location last week. Since it was my birthday, I went as decadent as possible and ordered a large hot Salt Mocha for myself, a cortado for my wife and two tarts to share. It was a cool but sunny morning so we sat outside and enjoyed the sunlight and people watched. The interior was packed, loud, bright and had an awesome yet compact layout with a sleek design centering around the barista station centered in the space. Beverage - maybe the best espresso based beverage ever! Tarts - fruit and caramel goodies that paired well with the drink. People - lovely to see an entire bustling downtown full of friendly folk all looking like they are on their way to a job interview. I'm very eager to visit the other Onyx locations on return trips to NWA. Just another perfect little caffeine experience that helped me momentarily forget about turning another decade older.

Lovely spot in the middle of Bentonville with great coffee and drinks, food and treats, and a buzzing atmosphere great for doing work or for catching up with family and friends. Don't miss if you are in town (and like coffee).

I love coffee...maybe my palate isn't so sophisticated enough for their coffee. I love a pour over Guatemalan. The atmosphere is great but the coffee isn't my favorite.

I had a weird experience here where I tried to pay for my single hot chocolate with a $20 bill and the cashier said they don't give back change, could she keep it? Seemed dishonest to me- especially since they are putting you on the spot asking you for a $15 tip on a $5 product. I took back my cash and used Apple Pay instead.

A place should not make their customers stand in line, give them a menu with food items on it, then tell you they are out of food when you get to the counter. Put a sign up, take the menu away, shout to people, or better yet don't put the food on the menu.

Ask a local where to get great coffee, and seemingly every single person will go out of their way to mention Onyx. To me, it lived up to the hype! We got the full Onyx experience: coffee + breakfast + sun drenched patio all while on vacation. Hard to beat that. The "Tropical" pour over I got was flavorful, although VERY light in flavor, almost like tea. You know what? I'm here for it. I probably would've chosen an Ethiopian if I got another one, but it was still a potent, tasty jolt to get going. The breakfast sandwich came out and at first I was like, "aw man." It looked a little small, and the croissant looked too dark. One bite in and I remembered looks can be deceiving; this was a ridiculously good breakfast sandwich. Pickled veggies, eggs, bacon and some kind of aioli like sauce all came together wonderfully. The atmosphere is good too; very trendy and I mean that in a good way. Lots of natural light, and beautiful black and white mini tiled counters in the middle. It's a huge space, especially when you count the outdoor patio where we enjoyed watching all the mountain bikers and business folks hustling and bustling in and out. One regret? Not taking some beans home as that's a staple of vacations for me, but I must just be a little rusty after a little time off of traveling. Overall we were impressed by the caffeine scene in Bentonville, and like the locals said, this was the top spot.

This is literally such a cute space! The interior has a modern, industrial vibe with dark wood and geometric patterns throughout. The design works cohesively with the variety of seating spaces. The outdoor seating is where it's at though, because the patterned table and booth-like seating are absolutely adorable. The latte art was perfection and so aesthetic. I ordered the Hail Fellow Well Met, which had a unique browned butter flavor. I do feel like the drink I ordered wasn't necessarily anything special and I choked on the powder at the bottom of the drink. However, the space and vibes made up for it!

The service was great and friendly!! We came in for coffee!! We totally recommend this place. The ambiance is cozy!!

Just bought 2 cups of house brewed coffee. They are so sour and bitter! No coffee aroma at all. Never had such bad coffee before. This really spoiled my morning. Make me wonder if the grounds is re-used? What bean are they using?

Their Southern Weather coffee bean pack is my favorite gift for out-of-towners!! Also, you must try their Vegan Curry Kolache! It is delicious

Grabbed breakfast here during our stay in Bentonville. We grabbed a few coffees and some breakfast items. I did feel like the food was a little pricey, but everything was delicious. I got the seasonal latte and it was incredible. We also got a breakfast sandwich and quiche, which were both very good. We were still hungry, so we also got a churro cruffin, which was also delish! Definitely recommend a stop for coffee here!

We love Onyx in bentonville and Roger's when we are in town. In Bentonville this time- Saturday morning there was a farmers market downtown so the road in front was closed and booths set up for vendors. Inside the line was long but moved fairly fast. We snagged some outside seating in the shade - great people and dog watching! Really loved the ham and cheese croissant, breakfast sandwich, banana bread we shared. I am a huge fan of the iced Hail Fellow Well Met- kids loved the smoothie! Great vibe, clean bathrooms, enjoyed our visit and for sure will be back!

Awesome aesthetics and coffee. Brought out of state friends here who also loved it. Always a treat.
