L.C.
When we were planning the rehearsal dinner for my son's wedding (summer before last) we could not find anyplace that would let you bring in your own food. Everywhere required you use a licensed caterer - sometimes only ones on their list. A few told us it was a state health law, another said it was for their insurance. You might check a rec center and see if they allow food & alcohol - we were looking for something fancier.
