I just booked one at Goose Island on Clybourn for 30-35 people in May. It looks like you're going to be in the minimum $25-35 per person range anywhere you look. My son and daughter in law wanted bar-type food, and Goose Island has a nice selection of private party rooms and offers their mini-burgers as one of the choices on your buffet (virtually all the places we looked at will serve buffet-style and have various drink options.) We also looked at Jake Melnick's, Jak's Tap and Mon Ami Gabi.
