I am looking for a place to throw an engagement party for my friend and her fiance. There are about 20 of us standing up in the wedding, and hoping most of us will pitch in for this, and about 55 total people invited for the engagement party. we want this to be fun, not very formal, but drinks, food, and just a time for people to chat and relax. Does anyone have any good venues around the Chicagoland area. (I would say as far west as Naperville to Chicago).
