Abstract: A food service kiosk is provided in the shape of a vehicle wherein the engine compartment is used for storage of enough water for food preparation and subsequent cleanup without leaving the food service site. A three-hole sink, a hand sink and a mop sink are located within the body section of the food service kiosk. Gray water from the three-hole sink drains into the mop sink which drains into the gray water tank. The engine compartment provides storage room for a fresh water tank, a hot water heater and a gray water storage tank which is not available in a conventional food service kiosk. Water from the mop sink drains into the gray water storage tank. If required for an extended stay at a food service site, a trailer can be attached to the rear end of the food service kiosk which contains a large fresh water storage tank for resupplying the fresh water tank in the engine compartment.
