They are meant for quick convenient food purchases. They make sandwiches to order and offer prepared foods and drinks ready to heat and serve, sometimes served on premises, typically in an alcove with a few small tables, often using disposable plates and plastic cutlery. They often have hot food and salad bars. They often sell soda and juice, give paper napkins and plastic forks, so that one can have the choice to consume the food at home, in a car, on a park bench, or sometimes at a table right on premises.
