I thought about that too and asked the venue if I can do it and they told me I need to provide a catering license for whoever does it and I don't have one of thoseYou could always use the kitchen and make them! I toyed with the idea of having like a potluck at our wedding but i got shot down. People on the wedding business don't hurt for money that's for sure!
I can get another caterer that's cheaper but it's still expensive lol
