"The man behind this humble sliver of a restaurant is none other than Albert Adrià, who, with his brother, Ferran, introduced molecular gastronomy to the world at El Bulli. That famed three-Michelin-star spot shuttered in 2011, but the chef now operates five eateries—all within blocks of one another—in the neighborhood of Sant Antoni. Bodega 1900 pays homage to the quintessential Spanish tradition of vermouth and tapas. But given that Adrià is at the helm, expect the highest-quality ingredients and an atypical approach. (Case in point, the olives here are actually made of gelled olive juice fashioned to resemble solid green olives.) There’s also an excellent selection of Iberian ham and local cheeses. Reservations are essential."

"Escape the hordes of tourists and head east of the city center to Poblenou, a quiet, leafy, residential neighborhood that boasts a number of excellent under-the-radar restaurants. Among them is this gem just off the Rambla del Poblenou—a warm, brick-walled space known for its stellar seafood-laden rices and fideuà (both are similar to paella, but the rices are a bit soupier, while fideuà is made with noodles). Chef Hug Pla Cortes serves up huge steaming pans of the stuff—sharing is compulsory—and his signature Vulcanus black smoked rice, teeming with prawns, mussels, and mushrooms, is a must-order. There’s also a lengthy list of tapas. The menu conveniently outlines which dishes are gluten- or dairy-free, vegetarian, and child-friendly."

"For oceanfront dining, Agua is a good bet among the tangle of so-so restaurants lining the city’s beaches. The Mediterranean menu focuses on fresh, simply prepared seafood, and there’s also a quality selection of Spanish rice dishes, steaks, and salads. The terrace sits right at the edge of the sand—and as you might expect, it's a hot ticket in warmer weather, so book ahead accordingly. Rumor has it the service here can be hit or miss, but you might not mind if you keep your eye on the sapphire Mediterranean and your focus on the celestial flavors. Vegetarian options are also available."

"Set on one of the city’s prettiest streets, the café-filled Carrer d’Enric Granados, this trendy bistro is open for breakfast, lunch, and dinner—but prime time is early evening, when locals stop by for a drink at the long white-marble-topped bar. It’s an ideal spot for a glass of wine—the daily pours are listed on the chalkboard—and pica pica (small bites). There’s also a restaurant at the back with more formal seating. You’ll find a sophisticated take on typical Catalan tapas and dishes (the burger is also particularly good). The bar seating lends itself to solo dining and exquisite people-watching."

"In the increasingly gentrifying El Raval neighborhood, along the leafy main avenue of Rambla del Raval, a whole host of restaurants, cafés, and bars are popping up. Among them is this intimate bistro from noted Catalan chef Carles Abellán, which takes a refined approach to traditional home cooking without being pretentious. To that end, the narrow dual-level space, a former bodega, is simply decorated with rustic wood furniture, forest-green walls, and a ceramic-tiled, marble-topped bar. The menu is divided into categories of small dishes—From the Sea, From the Mountain, From the Orchard—plus a few versions of classic Spanish stews. Leave room for the homemade desserts: The soft, silky Brie cheesecake is divine. Reservations are essential."

"You can grab pizza, pasta, and salads here, but most folks come to El Laurel for just one thing: the empanadas. Mix and match among 15 different varieties priced at just 2.20 euros (about $2.50) each. The flavor combinations are far from typical: There’s the Negrita, black pastry made with cuttlefish ink and stuffed with cuttlefish, tomatoes, mozzarella, and basil; and the Yello, its carrot-flavored dough filled with plums, bacon, mozzarella, and almonds. Meat lovers will dig the Dino, a spicy blend of diced veal, onion, sweet potato, and chili pepper. And for dessert, there’s La Dulce, with apples, brown sugar, cinnamon, raisins, nuts, quince, and red wine. Movie posters line the bright red walls, a nod to the Renoir Floridablanca movie theater right across the street."

"Set among the labyrinthine streets of the Gothic Quarter, this café offers a delicious selection of cakes, tarts, cookies, and other desserts—all baked by nuns from convents and monasteries around Spain . There are truffles from the sisters of Valladolid, cider cake from Santa Inés of Seville, and tea biscuits from the Convento Madre de Dios in Cáceres. Enjoy them with a cup of coffee or pot of tea, or try the famous hot chocolate. You can get a table upstairs, but it’s down below that you’ll want to score a seat: The space—a medieval-era Jewish bathhouse—features ancient stone walls and high vaulted ceilings. Live classical music concerts are occasionally held there, making for one of the more magical places to indulge your sweet tooth."

"Tucked inside a renovated former 19th-century factory near Passeig de Gràcia, this temple to Spanish gastronomy is housed in a breathtaking modernist masterpiece, with soaring vaulted ceilings, vintage lighting fixtures, ceramic tiles, and mosaics. Each of the four eateries inside has a distinct design and cuisine: La Llotja specializes in seafood; La Brasería is all about grilled and a la plancha meats; La Paradeta showcases Iberian cheeses and cured meats; and the buzziest spot, La Tapería, serves up hot and cold tapas. The central hubs are the Wine Bar and the Beer Bar, where you can sample a variety of local Catalan drafts. And at the intimate circular Oyster Bar, you can taste famed Galician oysters, as well as caviar, Norwegian salmon, and king crab."

"It doesn’t get more traditionally Spanish than tapas and vermouth, and Arola offers a great introduction to both. Reserve a table on the breezy terrace—with views of the ocean and Frank Gehry’s iconic fish sculpture—and prepare to while away a Sunday afternoon enjoying chef Sergi Arola’s signature SVT menu:Sunday Vermouth & Tapas. Things kick off, naturally, with a vermouth cocktail; here it’s served in an adorable miniature soda bottle with a tiny straw. A whirlwind of classic Spanish dishes follow: patatas bravas , marinated sardines, fideuà (a traditional dish of seafood atop noodles), paella (teeming with shellfish), and a whole sea bass cooked in salt. The 10-course menu, plus desserts and cheeses, is a steal at 60 euros (about $67), and you’re guaranteed not to be hungry for dinner."

"La Xula Tapería Set in the trendy Gràcia neighborhood, this lively, convivial tapas bar is a magnet for hip locals seeking a modern twist on traditional Catalan cuisine. The creative young kitchen staff turn out an array of fresh, inventive, generously portioned dishes at surprisingly affordable prices. Start with the salmon tartare with wasabi ice cream or tuna tataki on flatbread; mains include grilled octopus nestled atop sweet potatoes and drizzled in a smoky olive oil, and cannelloni stuffed with traditional butifarra sausage and mushrooms. Prices range from 4.50 to 12.90 euros (approximately $5 to $14). Service is friendly and efficient."

"After a day spent exploring Montjuïc's gardens and museums, this cozy corner restaurant in nearby El Poble-Sec makes for an ideal dinner stop. Simply decorated, with bright green walls, a long wood bar, and a handful of tables, La Platilleria doesn’t have a fixed menu; rather, the kitchen offers a daily selection of seasonal, locally sourced small plates. There are Spanish stalwarts like patatas bravas , pan con tomate , and Ibérico ham, but it’s worth trying the specials, which might include a rich dish of braised oxtail atop polenta, or osso buco with sweet potatoes. A small but well-curated selection of Spanish wine, cava , and craft beer is available—if you’re feeling daring (or thrifty), order a 3euro ($3.35) pinguino , a penguin-shaped carafe of rustic local wine."

"Restaurants abound in the heavily touristed Gothic Quarter, but few of them are particularly good. Irati is one of the exceptions, a bustling spot popular with locals thanks to its excellent pintxos , traditional Basque tapas served on bread and speared with a toothpick. There’s seating in the back, but you’re really here for the experience of eating pintxos , which means standing shoulder-to-shoulder at the bar and helping yourself to the buffet of bite-size offerings. A sure bet is the jamón , lightly drizzled in olive oil, and the blue cheese topped with quince paste and walnuts. Save room for the hot snacks, like ham-and-cheese croquetas , which are brought out at regular intervals from the kitchen. And don’t toss your toothpicks—that’s how the bill is tallied."

"Forget Google Maps: You’ll quickly locate this venerable tapas bar in El Poble-Sec by the line out the door. With standing-room-only space for just 20 people, this sliver of a spot fills up fast—and stays that way until closing time. In a room lined floor-to-ceiling with bottles of wine, liquor, and pricey vinegar, you can sample a dizzying variety of tapas and montaditos (small bites served atop slices of bread). Many of the ingredients—namely the mussels, sardines, and tuna—come from cans, which sounds suspect, but Spanish conservas (tinned food) is actually of the highest quality. The cheeses—all fresh—are also top-notch."

"Speedy Tapas on the Cheap at La Esquinica A lot of the best places to eat on the cheap in Barcelona are a little out of the way. For a truly local experience, and the fastest tapas in town at ridiculously cheap prices, try on La Esquinica (the little corner) for size. Do as the Barcelonans do and drink vino turbio (house wine shaken until it's frothy) and sample a little bit of everything. Croquettes, bombas, patatas bravas (potatoes with garlic mayonnaise and hot sauce), stuffed mussels, and grilled Spanish meats, all prepared in house and served up in a matter of minutes. Note: Like so much Spanish bar food, this is not light cuisine, or particularly vegan or vegetarian friendly. Also, if you go during typical Spanish meal times on a weekend (2-3pm, 8.30-10pm) expect to wait in line to be seated. The nearest metro stops are Vilapicina and Virrei Amat, L5."

"Though Barcelona is hardly the epicenter of paella (that would be to the south, in Valencia), this hands-on culinary workshop/dining experience offers a fine introduction to what’s arguably Spain’s most famous dish. Set in an appealingly hip Raval-area space featuring soaring ceilings, exposed brick walls, and industrial lighting, the class starts with a welcome glass of cava along with a brief overview of paella from founder Alex Betolaz and chef Alex Villar. Don an apron at your cooking station, but don’t expect anything too labor-intensive; ingredients are, for the most part, already prepared, though you will do a bit of chopping, pouring, and stirring. (You can book your paella preferences ahead of time, and vegetarian options are available.) Then you’ll gather around a long wood table and sample various Catalan specialties along with your paella (and there’s usually plenty of sharing going on). Choose from three different paella-making experiences, starting at €50/per person for two courses and going up to €85 for multiple courses plus unlimited wine."
