BUFFET

A buffet is properly a cupboard, sideboard, or closet used to hold china, crystal, plate, and the like. The word is also very commonly applied to the space set apart for refreshments in public places, and to a spread of food from which diners serve themselves to a selection before going to eat elsewhere, as distinct from having the food laid out on the table at which the diners sit.
