You'll find all kinds of positive reviews online, I assure you they are all fake, probably written by the owner.
Slabs of plain seitan on rice. Chunks of tofu on rice. Whitest bread ever. Weird written manifesto as you enter about importance of local and organic produce, yet everything is super processed and bought from Mercadona (kitchen is open, you can see the cans and boxes very easily). In any other city, no one would tolerate this, but Barcelona has the worst veg restaurants anywhere I've been in the world, so I guess people put up with ridiculous standards.
Cons: food , food , food
