Does the event venue allow outside vendors or caterers to be used?

Discover wedding venues in North Carolina that allow BYO catering. Does your venue allow you to have an external catering service or do you have to use one of your contract catering services or your own catering service? How has this affected prices? External catering only means food that is not served by the venue. Most venues aim to be a one-stop shop for your event, as they offer the space, basic services, food and drink.
