This is the best place for vegans in Rio de Janeiro, really, they are perfect...even the cashier was wearing a t-shirt that had written "Animals are friends, not food".
You have to go upstairs for the buffet. There are so many options that you will gonna wish eat all the dishes... they have sushi and desserts too!! All you can eat for R$26.
My boyfriend and I were a little "sick" by the caipirinhas the night before, but still we tried to taste all the dishes. So, yes, this was our paradise.
The staff is very polite and friendly. The space is small but with a nice atmosphere.
The street is a bit hidden, you gonna need google maps.
