A buffet (IPA: [ˈbʊfeɪ] in the UK, IPA: [bəˈfeɪ] in the US, from French: sideboard) is a system of serving meals in which food is placed in a public area where the diners generally serve themselves. Buffets are offered at various places including hotels, restaurants and many social events. Buffet restaurants normally offer all-you-can-eat (AYCE) food for a set price. Buffets usually have some hot dishes, so the term cold buffet (see Smörgåsbord) has been developed to describe formats lacking hot food. Hot or cold buffets usually involve dishware and utensils, but a finger buffet is an array of foods that are designed to be small and easily consumed only by hand, including cupcakes, slices of pizza, foods on cocktail sticks, etc.
The essential feature of the various buffet formats is that the diners can directly view the food and immediately select which dishes they wish to consume, and usually also can decide how much food they take. Buffets are effective for serving large numbers of people at once, and are often seen in institutional settings, such as business conventions or large parties.
Since a buffet involves diners serving themselves, it has in the past been considered an informal form of dining, less formal than table service. In recent years, however, buffet meals are increasingly popular among hosts of home dinner parties, especially in homes where limited space complicates the serving of individual table places.
The buffet table originates from the brännvinsbord (Swedish schnapps, or shot of alcoholic beverage) table from the middle of 16th century. This custom had its prime during the early 18th century, and was developed into the more modern buffet around the beginning of 19th century. The smörgåsbord buffet did not increase in popularity until the expansion of the railroads throughout Europe.
The smörgåsbord table was originally a meal where guests gathered before dinner for a pre-dinner drink, and was not part of the formal dinner that followed. The smörgåsbord buffet was often held in separate rooms for men and women before the dinner was served.
