Dusty's Cellar in Okemos, MI - good food, excellent service. Very intimate and romantic. Go there if somebody else is paying.
For pizza, I like Buddy's and Dolly's.
Cady's Grill in Ypsi is good. They have a really good chicken salad with Michigan cherries and other stuff in it. Their butternut squash soup is also delicious.
Culver's is good for "fast food." Much tastier than McCrappy's, although I doubt Culver's burgers are bionic, which is kind of a bummer.
Xochimilco's in Detroit, because they're open late and they give you tons of food for cheap. I always get the fajitas. Don't talk to the beggers outside.
The State Room at the Kellogg Center in East Lansing. We have Sunday brunch there and once a year they have Lobster Night, which my mom and brother say is awesome. They didn't take me with them, so I wouldn't personally know. :-P
