I ended up spending about 5 days in Belem and every day I went here cos it was so good. The menu varies each day and it is awesome. The desserts are also delicious and the empanadas are the best I have had in South America (I've tried a lot). You want want to eat anywhere else in town after you go here.
The map is wrong though. It's on the other side of Pres. Varga. You will see it.Pros: All vegan, Menu changes daily, Green smoothies
Cons: A bit expensive but worth it
