You won’t find a more glorious buffet culture anywhere in the world than in Singapore where walk-in buffets are offered at various restaurants & hotels.
There are many times of buffet, but the more popular type is the free-form, all-you-can-eat buffet. Customers pay a fixed fee and help themselves to as much food as they wish from an open buffet or ala carte buffet.
In a YAKINIKU charcoal grill / steamboat buffet restaurant, diners order several types of raw ingredients which are brought to the table. The ingredients are cooked by the diners on a grill built into the table . Some of these restaurants utilize a high-end 'smokeless' technology. This eliminates the odour of the girlled items clinging on to your clothes and hair.
Another form of buffet occurs in a Dim sum house, where patrons make their selections from a wheeled trolley containing food that circulates through the restaurant.
A fourth type of buffet is a Churrascaria . These are restaurants that serve grilled meat, many offering as much as you can eat: the waiters move around the restaurant with skewers, slicing meat onto the client's plate. One popular restaurant is of course Brazil Churrascaria which pioneered this concept in Singapore.
