I went to the Kalamazoo Beer Exchange one time and agree with dirtracer's assessment. I liked it a lot. Cool atmosphere, entertaining to watch the prices change, lots of good beers on tap, and damn good food. The nachos were awesome.
Bell's brewery is always a good choice too. There's a country bar in downtown that's supposed to be pretty good too but I didn't make it there when I was in town. The Wild Bull I think?
