One of my favorite places - I eat here every time I visit Sao Paulo, sometimes 2-3 times (most recently in December 2014). They have other locations in the city, and this is my favorite - with the largest selection of food and a large number of tables. Although other reviews mention that vegan dishes are indicated, I didn't see this on any of my trips here, but the staff are helpful and point them out. The price is excellent - about $10 US (at current exchange rates) for all you can eat buffet. Salads and hot dishes are excellent. Desserts look great, and some also taste great, but the best is the fresh fruits. I highly recommend this place if you're looking for a big lunch and aren't trying to lose weight (if you are, you will need lots of will power).
Cons: Vegan dishes not indicated
