PROBLEM TO BE SOLVED: To orderly park each of meal serving wagons in a preset parking position when the autonomously travelable meal serving wagon capable of being remotely controlled via radio communication is guided. SOLUTION: The respective meal serving wagons are returned to a parking place 5 near a kitchen in order based on a classification (group) preset for each of the meal serving wagons, and parked at shorter front, back, right and left intervals among them in order from a back position in the space of a preset parking place. When an elevator 2 is used halfway on the travel of the location of the meal serving wagon, the meal serving wagons are traveled by using the elevator 2, in order from the meal serving wagon to be parked in the back position of the parking place 5. This enables the meal serving wagons to be orderly parked in preset parking positions so as to be smoothly usable in the next use, and enables the operation of loading the meal serving wagon with meals to be performed without any mistakes over a short period of time.
