A cafeteria is a restaurant serving ready-cooked food arranged behind a food-serving counter. There is little or no table service. Typically, a patron takes a tray and pushes it along a track in front of the counter. Depending on the establishment, servings may be ordered from attendants, selected as ready-made portions already on plates, or self-serve their own portions. Cafeterias are common in hospitals, corporations and educational institutions. In Italy it's very common and known as "mensa aziendale".
