ABSTRACT:
Disclosed is a plate warming apparatus for use in keeping food warm in a restaurant. The invention has four primary components: a serving plate; a heater assembly; a plate adapter for coupling the plate and heater assembly; and a base fixture that enables the adapter to be selectively coupled to the heater assembly. These elements allow the heater assembly to heat the underside of a serving plate and, thereby, keep food warm as it is delivered to and consumed at a user's table. The invention allows the heater assembly to be uncoupled from the underside of the plate and recharged as necessary for reuse on other serving plates.
