one of my favourite spots in Barcelona. Definitely one of my go-to-joints when visitors are in town. Tapas - family style! Great food, great prices, but it's easy to go over board when ordering tapas, especially when they're good...be careful!
The only downside is, it's always packed. They don't take reservations, so you basically have to wait in line until your number is called. To me, long lines are a good sign for good food. just saying.
I highly suggest the pimientos de padron (look like deep fried jalepenos, but they aren't spicy), chipirones (deep fried baby squid), pulpo gallego (Galician style octopus), & los tigres (stuffed mussels - my personal fav).
The restaurant is definitely off the beaten path of tourists, but well worth it. The waiters get very busy, but they've always been friendly.
