I'm a little surprised by the dislike for Founders but I can't complain about it. some of the best beers around, and if you ever get the chance to hit the main brewery in Grand Rapids, do it. Its the best of any of these places I've been to (and I've been to many), with outdoor seating around fires in the winter. and in GR, you can't walk more than 20 yards before hitting another brewery/bar/pub. I get that Founders is big now and so its not cool to think they're the best, but they can compete with anyone.
personally I've never been in a brewery I didn't like. will be at
Draught Horse Brewery for happy hour today. also,
Witch's Hat Brewing is a place I hit every couple of months. there are just so many around here that I forget,
Ascension Brewing in Novi has good beer and some tasty street tacos. I visit the SW corner of Michigan a few times a year and there's probably 5-10 breweries I hit on that side, all with their own charm and good beer.
