cafeteria
A dining area where customers serve themselves from stations with ready-made food.
A cafeteria is a dining area where customers select and serve their own food from various buffets and stations, then pay a cashier and bring the food to their tables.
Customers select and serve their own food before paying a cashier. The food is already available at buffet or service stations.
Customers then carry the meal to a table. This differs from a menu-based restaurant where wait staff serve the seated diner.
