My wife and I had lunch here today, and it was great. We got the set menu: soup with noodles and seitan, mains - tofu with rice (filled with onion, green peppers and seitan) and potatoes with soya-based mayo, and seitan with the same things. We also got desert as part of the set menu, which was like a pineapple rice pudding. It was affordable, and we were stuffed. Brush up on your Spanish, as the waiter couldn't speak English at all, but we managed to get by anyway.
Cons: Not 100% vegan
