I am looking for suggestions for a rehearsal dinner site for June. We expect between 30-50 people. I need to keep the cost down and prefer something informal so that people can really spend time visiting before the wedding. I would love a BYOB place but have had little luck so far. All suggestions are appreciated as I do not live in PA and know very little about Philadelphia. The wedding will be at the Park Hyatt at the Bellevue which I believe is downtown. I would like something not too far away.
