In Madison, check out Vintage Brewing. It's one of the best brewpubs I've ever been to. There's one location off the beltway and a smaller one right off campus on Frances and University.
Also hit up the Ale Asylum, and Tyranena Brewing is a short drive east of Madison.
Finally, yes, yes, we're cheeseheads, blah blah, but seriously - New Glarus is a short drive from Monroe, which is home to some of the finest cheesemakers in the world. If you don't feel like a road trip through the western Wisconsin countryside, however, I hear Edelweiss Creamery just opened a store in New Glarus. Edelweiss's Swiss cheese just beat the best cheesemakers in Switzerland to be named best Swiss in the world.
