If I could, I would give this place 6 stars/cows - it is better than other places I've rated 5 cows! The selection of food is incredible - a large table of salads and another of entrees, and a smaller table of desserts. Each dish has a little card with symbols O,L, or G, denoting eggs, milk-based products, or gluten. Everything I tried was very tasty and fresh. Good thing it was per kilo and not all-you-can-eat, or else I would have gained several kilos! The atmosphere is very relaxing and nicely decorated. If you're in central SP near the Luz station, you have to try this place. Or make a special trip here - it is that good. I'll certainly be back every time I'm in Sao Paulo. Some other reviewers have commented on the long line for the cashier. I was there on a Saturday and there was only a 1-2 minute wait to leave, but I can imagine on a weekday that at certain times it could be a wait to pay.
Cons: Only buffet lunch
