Flava I hope you have tickets in the student section - best place to be in the Big House.
I honestly couldn't tell you where to party in Ann Arbor. I moved there to do my internship at the University Hospital and then worked there. If I had moved there before that stretch I would have some answers.
Good luck, Flava.
Oh, but if you have time to get a decent meal the Real Seafood Co. downtown would be my pick.
