Cervecería Catalana is the best pintxos bar in the Eixample — a long marble counter loaded with creative pintxos, alongside proper tapas, excellent patatas bravas, and a broad selection of Catalan beers and wines. The kitchen works from morning to late night without a break, which makes it uniquely useful in a city where many places observe a strict split between lunch and dinner service.
There is always a queue. It moves. The terrace on Carrer de Mallorca is excellent for people-watching in the Eixample. Book online if you want a proper table; walk-ins at the bar are always possible.
