Cafeteria

n. restaurant, small diner, public dining room

A cafeteria is a type of food service location in which there is little or no table service, whether a restaurant or within an institution such as a large office building or school; a school dining location is also referred to as a canteen or dining hall. Cafeterias are different from coffeehouses, although that is the Spanish origin of the American word.
