Couple suggestions ...
If you are driving, and want to pick up some great beer and/or have a bite to eat), I highly recommend stopping at:
From the East:
Old Nation in Williamstion, MI (20 minutes from MSU) - M43, Boss Tweed - Best NE IPA's in MI - can have lunch as well
- can find M43 in most places that sell beer, but Boss Tweed and some others are brewery only
From the West:
Transient Artisan Ales in Bridgman (just off 94, a little over 2 hours from MSU) - really great IPA'S, PA's, wild ales, saisons - check their hours though, often don't open until 4
Founders in Grand Rapids - can have lunch, and pub only beers available (a little over an hour from MSU)
In East Lansing:
Breakfast/Brunch, good bar food Beggar's Banquet
Beer Hopcat, Crunchy's
Mexican el Azteca
