Midwest Munchies

Yo -- I'm going to be in Ann Arbor and Chicago in June on business travel for meetings of the Butcher Specialty Association (BSASS) and the Boudin/Sausage Makers (BDSM).  I'm going to try to go to Charlie Trotter's or maybe one of Rick Bayless's places, but plans are still fluid.  Chicago should be easy, but Ann Arbor (UMich) is tougher.  Any suggestions, O loyal readers?
