The food is really interesting.
But the place is sultry, specially in the Rio's summer.
The food cooked at there ir vegan, but the restaurant sells no-vegan industrial third-party products, like non-vegan wines, milk candy and honey-based desserts. Be careful if you are vegan.
Beyond some weight limit the price you pay does not increase anymore. I like to go starvated at saturdays (for not sleep at work) and eat two full plotes paying a little more than US$10.
Cons: Not wheelchair accessible, Sultry place, specially in summer, Kitchen has bad appearance
