Some friends and I are going to be in Chicago for New Year's and are looking for any good bar parties around the Magnificent Mile. We would only like to spend approx $100-$150 for an open bar party. We would also prefer a place that has a dance club as well as a bar setting and is more dress casual and not so much suit and tie. We already have hotel reservations and are going to the Suns vs Bulls game. Any help would be much appreciated.
