A food serving system for delivering prepared meals to locations remote from the point of preparation which includes a mobile cart having its own low voltage rechargeable power pack that may be utilized to make the cart self powered. The cart has a tier of shelves for carrying removable, generally flat, individual, food serving trays. Each shelf is provided with one or more thermally isolated heat transfer devices which may be energized when a tray is placed on the shelf in the cart. The heat transfer devices are intended to maintain the food in selected dishes and bowls at the desired serving temperature for extended periods without affecting the temperature of the foods and beverages in other dishes, bowls and cups on the trays, so that the food remains at the proper serving temperature. In one embodiment the trays have holes at selected locations which allow the dishes directly to engage the heat transfer devices, while in another embodiment the trays have plates of high thermal conductivity, which support the dishes and engage the heat transfer devices.
