Onyx Coffee Lab

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

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.

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!

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.

I’ve been a fan of Onyx coffee for several years now. Today was my first time ever at the Bentonville Location. After trying all 3 in the NWA, this is my favorite for sure. Great location in the downtown square. The inside was awesome with a darker moody atmosphere and well done interior. Great space to work and enjoy your coffee. Per usual, the drinks were excellent. I highly recommend the Onyx delight and the Ham and Cheese Croissant. Will be back

Super fast,foamy, tasty, coffee! Honey croissant was great and not too sweet without the extra honey drizzle. Clean and tasteful design. Nice woodwork to offset the beautiful tile hard scape. Efficiently moving people through the line, the staff knows exactly who ordered which items. I like the “center kitchen” area where you can watch them all work. Nice gift options for us tourists too! Most of all, it’s great coffee in a great location with great service! Don’t miss it! Day 2- discovered they have breakfast bowls! What a huge win for a great start to the day. The chicken tiki masala green bowl was amazing and bursting with flavors!
