ABSTRACT:
A food service tray assembly including a tray, a hot food dish, and an insulated dome. Hot food is served onto the dish, the dome is preheated, the food carrying dish is set on the tray, the preheated dome set over the dish, and the tray system delivered to the intended consumer. A thermochromic member disposed in a heat conductive sleeve is mounted in the lift knob of the dome. Thus, without lifting the dome, the server and/or the consumer can readily determine from the color of the member whether the covered food is still at a safe heating temperature.
