A cafeteria in Gretna is a type of food service site, where there is little or no waiting staff table service. It might be in a restaurant or within an organization such as a large office building or school. Cafeterias in Gretna are generally different from the popular coffeehouses. In cafeterias, instead of table service, there are food-serving counters/booths and also one will find a queue or arbitrary walking paths for customers to line up and order for food and beverages. Customers take the food they require, place it on a tray and walk along to a place to sit. As these cafeterias require few employees, they are often established within a larger organization, catering to the customers of that organization.
