A quintessential carioca restaurant option is the 'kilo buffet', where food is selected from a diverse and eclectic spread of dishes, sides and sauces and the price is determined not by the individual selections but by the overall weight of the plate.

Frontera is one of the most celebrated of this variety of establishment, offering a mosaic of dishes from Asia, Latin America and Europe, hence breaking down culinary 'frontiers' by offering a global fusion. branches can be found in Ipanema, Leblon, Jardim Botânico and Barra da Tijuca, each offering a wide range of exotic and classic dishes, such as Mexican garlic chicken, duck in ginger sauce, shrimp with mango chutney and beef tenderloin in a white wine sauce.
