20 Best Tapas Bars in Barcelona, From Old-School Dives to the Avant Garde | Condé Nast Traveler

"The street-facing bar is colorful and lively while a pared-back dining room sits at the back, and people come mainly to drink—especially local Catalan and natural wines and vermuts—though the food is equally delicious: try the spicy steak tartare served in a brioche bun with pork jowl and smoked egg yolk or the warm leeks with hazelnut vinaigrette topped with Catalan mató cheese and sun-dried tomatoes; the chef’s tasting menu (three snacks, five dishes and dessert) is an unbeatable-value Catalan omakase at €49." - Isabelle Kliger
