Bar Cañete
This is probably the best tapas bar in Barcelona. It's very popular among locals, which is usually also a good sign. The food is great and the décor is very low key and cosy. The prices are extremely fair and the portions are generous. The restaurant only has 2 tables. The rest of the seats are in the long bar area. The waiters are kind. I love this place, and I can highly recommend it. But book ahead, unless you want to wait forever in a que.
