This was the best place we ate in Barcelona, and we enjoyed the experience so much we ate here twice. The place is full of a lively crowd of young locals and really fills out after about 9.30, as with most places in Barcelona. The atmosphere is very friendly and the staff speak good English, although the whole experience left me wanting to learn Catalan and move here permanently!
Seating is at a long bar, and you can choose cold pintxos from the counter or order up some of the hot ones from the menu. There's also a menu of larger dishes (cazuelitas) which are about the right size for 2 sharing. The special cazuelita when we visited was pulpo a la gallega and it was absolutely delicious! The octopus was really nicely cooked and very well spiced. Other highlights were the spinach croquetas, grilled prawn and artichoke skewers with satay sauce, veal with chimichurri sauce and pork loin with mustard sauce. It's so hard to pick favourites though- every pintxo was so tasty and interesting, with a wide variety on the menu and seemingly a real effort made to go way beyond the standard tapas options.
There was also a good selection for vegetarians, particularly from the cold pintxos. You could really spend all evening here, passing your beer glass across the counter for refills and ordering as and when you want. With the prices from 1.70 to 2.90 per dish it's also perfectly possible to without breaking the bank.
