Cheap for quality. Try the soja little hamburger, it's my preferred!

A big all-vegetarian buffet with a lot if seats, Many things to choose from, even for vegans, amazing vegan banana bread! And really inexpensive. We'll be back.

After almost going crazy trying to find this place through the street of São Paulo, I had the chance to taste a really good food.

All the vegan options are marked and it is a all-you-can-eat buffet.
Be sure to try the vegan sausage and the dessert made from coffee.
Can't wait to come back.

gorgeous, down-to-earth restaurant, allucsbeat for 19 Reais (weekends 22)!
Yum!

Agreeing with most of what's being said, I have to add: you guys have to prove the vegetal protein hamburger they make. It's perfect!
Oh, and the place is really clean and fresh, which is nice given the brazilian weather. Bathrooms and lavatories well cared.
They accept credit cards, VR ("Vale Refeiçao") and money, of course.
It's a really good restaurant to take carnivors friends and show them how amazing and diverse vegetarian food can taste.

complete buffet including juice (1 with sugar and 1 natural), full dessert bar, and a complete salad and hot meal bar. It's a great value for the money, that's for sure. As of this writing, it's R$18,00 during the week and R$20,00 on Saturday. Parking is tough to find in this busy Itaim Bibi neighborhood but it's one of the safest and most fun in São Paulo. The variety is outstanding, the quality pretty good. There's food for kids (french fries are a regular option), ice cream and fresh fruit on the dessert bar, and Brasilian-style vegetarian offerings for a low price.

This "Cachoeira Tropical" has 3 restaurants, only 1 is (supposedly) vegetarian. The other 2 serve fish and chicken in its buffet.

It has a nice buffet with salad stuff, a range of soy and veggie dishes, basic sushi, fresh juices and dessert. There is some meat options but quite small. Be careful because the dinner menu is completely different and offers a special shrimp dinner with no buffet. But it is a great lunch place!
