I have read a few things around the internet about restaurants in Barcelona where one pays a flat fee and can just go to town with the food, eating until no more food can be consumed. Does such a place exist? Ideally it would be awesome if a place had an all you can drink (soft and alcoholic) because regardless of the substance, I drink quite a bit. Wikitravel mentions a place near Sagrada Familia, but isn't very specific about it. Headed to BCN in the summer so I'm just looking for a few cheaper places to go, as I will be on a bit of a budget. Thanks a lot guys and girls!
