Buffet in Ipanema & Leblon

Run by a Dutch chef, Frontera offers more than 60 plates at its lunch buffet, which features a mouthwatering assortment of grilled meats, baked casseroles and seafood pastas, plus grilled vegetables, salads, fresh fruits and desserts. Sushi and the dessert counter costs extra. Dark woods and vintage travel posters give it a cozier feel than most per-kilo places.

After 6pm Frontera offers all-you-can-eat pizzas (served rodizio-style), for R$20 to R$30, depending on the day (it's cheapest on Wednesdays).
