The present invention relates to a trolley for transporting dishes to be served hot, including a thermally insulated compartment 1 provided with heating plates 2 of high thermal inertia and intended to receive the dishes 4 containing the food, the said plates including heating resistors 3 connected to electrical power supply circuits provided with adjusting means making it possible to turn off the current, characterised in that the adjusting means programme a continuous supply time tI for the heating resistors, then a sequence of cutoff and resupply times t1 and t2; tI, t1, t2 being chosen so that the plate reaches a requisite temperature Tp and is maintained there. <IMAGE>
