Abstract of the Invention A food service device including a food-carrying cart which can be stored inside a refrigerator is provided with elements for heating the food before meals are served. The electrical system is comprised of switching devices which actuate the heating elements depending upon the presence and orientation of food trays on the shelf of the cart; a self- aligning coupling which can supply electrical power to the cart's heaters when the cart is placed in the refrigerator; and a timer which controls the duration of time the electrical heaters are energized to warm the food prior to service, and provide a keep-warm timing sequence for holding the heated food within a refrigerated environment.
