It's a bar/pub that's focused on beers, you won't have any wine or drinks, just beers, best of the…read moreworld's beers. The place is very nice decorated, the ambient is calm, dark, very pleasing. They have a great selection of about 12 beers from the tap, and a huge selection of bottles from around the world. You will get lost on the beer list even if you are a beer expert, so you better ask the staff to recommend one based on your taste. The staff is friendly, and they really know their stuff.
If you are in Barcelona and are a beer lover, you should take the time to visit this place, is not close, though. So be prepared. The trip consists of train to Mataro (45 min from Barcelona Plaza Catalunya) and once in Mataro you can walk (15 minutes) or take a taxi (aprox 8 euros).
Btw: The place is highly rated on ratebeer.com's list of top beer destinations.
