Automat
From Wikipedia, the free encyclopedia
An automat is a fast food restaurant where simple foods and drink are served by coin-operated and bill-operated vending machines.
Originally, the machines in U.S. automats took only nickels.[1] In the original format, a cashier would sit in a change booth in the center of the restaurant, behind a wide marble counter with five to eight rounded depressions in it. The diner would insert the required number of coins in a machine and then lift a window, which was hinged at the top, to remove the meal, which was generally wrapped in waxed paper. The machines were filled from the kitchen behind. All or most New York automats also had a cafeteria-style steam table where patrons could slide a tray along rails and choose foods, which were ladled out of steaming tureens.
