Review: I stumbled across Gopal 2 years ago, and have been back a couple of times since. Small, completely vegan deli/cafe. They serve a variety of burgers, have bento style take away meals and a selection of cakes. Pretty cheap, and quite friendly (the staff sometimes came across as judgmental but maybe i caught them on a bad day). i've gone for a burger each time, they have an English menu too if you ask! Also sells a selection of vegan meats and cheeses which is pretty useful if you're staying in Barcelona self catering. Cheese cake is recommended.
