A cafeteria is a type of food service location in which there is little or no waiting staff 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 dining hall or canteen (in British English). Cafeterias are different from coffeehouses, although that is the Spanish meaning of the English word.Instead of table service, there are food-serving counters/stalls, either in a line or allowing arbitrary walking paths. Customers take the food they require as they walk along, placing it on a tray. In addition, there are often stations where customers order food and wait while it is prepared, particularly for items such as hamburgers or tacos which must be served hot and can be quickly prepared. Alternatively, the patron is given a number and the item is brought to their table. For some food items and drinks, such as sodas, water, or the like, customers collect an empty container, pay at the check-out, and fill the container after the check-out. Free second servings are often allowed under this system. For legal purposes (and the consumption patterns of customers), this system is rarely, if at all, used for alcoholic beverages in the US.Customers are either charged a flat rate for admission (as in a buffet) or pay at the check-out for each item. Some self-service cafeterias charge by the weight of items on a patron's plate.As cafeterias require few employees, they are often found within a larger institution, catering to the clientele of that institution. For example, schools, colleges and their residence halls, department stores, hospitals, museums, military bases, prisons, and office buildings often have cafeterias.At one time, upscale cafeteria-style restaurants dominated the culture of the Southern United States, and to a lesser extent the Midwest. There were several prominent chains of them: Bickford's, Morrison's Cafeteria, Piccadilly Cafeteria, S&W Cafeteria, Apple House, Luby's, K&W, Britling, Wyatt's Cafeteria, and Blue Boar among them. Currently two Midwestern chains still exist, Sloppy Jo's Lunchroom and Manny's, both located in Illinois. There were also a number of smaller chains, usually in and around a single city. These institutions, with the exception of K&W, went into a decline in the 1960s with the rise of fast food and were largely finished off in the 1980s by the rise of "casual dining". A few chains — notably Luby's and Piccadilly Cafeterias (which took over the Morrison's chain in 1998) — continue to fill some of the gap left by the decline of the older chains. Many of the smaller Midwestern chains, such as MCL Cafeterias centered around Indianapolis, are still very much in business.
