Abstract of the Disclosure A food serving system for rethermalization of the food and for delivering prepared meals to locations remote from the place of preparation, such as to patients in hospitals and in nursing homes. The system includes a mobile cart having its own rechargeable power pack that may be utilized to propel the cart. The cart has separate bays each having a tier or racks for carrying individual food serving trays. Each tray has one or more thermally isolated heat transfer devices which are selectably energized when the tray is in place on a rack in the cart. The trays are constructed to carry conventionally styled, removable dishes, bowls, cups, etc., that may be either disposable or reuseable. Preferably, each tray has a pair of heaters referred to herein as plate and bowl heaters and adapted to be operated by control means in either a continuous mode of operation or a rethermaliza- tion mode of operation. In the rethermalization mode of operation the manually selected heaters associated with trays in all bays are operated for a predetermined period of time of, for example, 25 minutes, to rethermalize the food from a frozen or at least cold state to a temperature on the order of 170°P.-180°P. Thereafter, the heaters in predetermined bays are operated cyclically to hold the food at the desired temperature range.
