There is a large warming kitchen, you would also have to use a licensed and insured caterer as there are strict rules about food handling and serving people in the facility. It is owned by M-NCPPC Prince George's Parks and Recreation, so you would have to call them or go to their rental office at the Ballroom to know if the day you want is available and complete your rental application. You can get more information online at pgelegantsettings.com
It has a kitchen and you can bring your own food. I believe you have to rent thru PG county Parks and planning.
