Catering and Alcohol


All arrangements for food services, menu selections, and payment must are made directly by the sponsoring group. The sponsoring group or the caterer is responsible for all clean up. This includes the catering space (refrigerator, freezer, and microwave), if used. Clean up does not include trash removal. Failure to clean up after any given event may result in additional service charges. The preferred caterers for TCS Conference Center events are the following:
