Abstract: An improved food serving cart of the type having a compartment for holding multiple trays of prepared foods having both hot and cold food and/or beverage portions thereon, the improvement including a vertically disposed cold reservoir for holding replaceable cooling modules, and multiple food tray holding racks attached inside the cart in a vertical column horizontally adjacent to and in thermal communication with the vertically disposed cold reservoir such that a first portion of each of the horizontal racks is in close proximity to the cooling modules and constitutes a cold zone and a second portion of each of the horizontal racks in spatially separated from the vertical cold reservoir and constitutes a hot zone.

Abstract: A knock-down tray rack having a horizontal base member, a pair of bow-shaped support members, and a pair of unitary side panels incorporating upright sleeve members at opposite side edges thereof for receiving the upright leg members of the support members, and being provided with opposed vertically spaced ledges for supporting trays thereon. The leg members of the support members are adapted to be easily telescopingly fitted in the corresponding sleeve members of the side panels so that the bow-shaped support members span the side panels and so that the bottoms of the leg members are securely received within corresponding socket members in the base member. The base member may be further supported by casters having mounting extensions extending into the open bottom ends of the depending leg members of the bow-shaped support members.
