To make the temperature in a pantry used for putting foods in lunch boxes higher so that work may be conducted easily.

The inside of a pantry 1 which is separated from the outside 3 by a partition wall 2 is controlled to an easily workable temperature by means of an air conditioner. In the pantry 1, many cooled service tables 51-5n are arranged for setting lunch. Each service table 5 has a heat exchanger 9 and a top board 11 having superior thermal conductivity and cooled by a low- temperature antifreeze liquid supplied from an outdoor antifreeze liquid cooler through a brine tube 6. Since the foods placed on the top board 11 and put in lunch boxes are cooled from the top board 11 side, the foods can be prevented from being changed in quality and putrefied even when the temperature of the pantry 1 is high.
