Kilos are restaurants where clients serve themselves at a main table and then weigh their plates and get billed accordingly by weight. Kilos often offer a 'fixo' rate, which allows for unlimited servings at a fixed price - normally this rate is not plainly visible or advertised and must be inquired about. Most kilos have a basic churrascaria as well, offering a nice variety of meats. These cuts are usually located separately from the main food tables, and meats are cut and prepared to order.

High-end kilos also offer sushi as part of the buffet - additionally, they can offer sashimi of salmon or tuna, but these must be specifically asked for and are weighted on a separate dish, and are billed at a higher rate.
