Chicago area brewers

Revolution and Half Acre if you're limiting it to just breweries in Chicago.

ETA: Goose Island brewpub on Clybourn typically has shite we aren't gonna get down here.

Here's what I would do. Bell's beer is not actually from Chicago, but Kalamazoo, MI, and is available in IL. Even though it's supposedly going to be distributed here starting in May, I'd still be like, "Hey dude, score me some Bell's".

3 Floyd's, Great Lakes and Pipeworks will be on the shelf. Half Acre Daisy Cutter is a solid IPA and worth getting. I'll add Off Color to the mix. Dino S'mores is fricking excellent and some of their Saisons are very good too. Goose Clybourn will fill growlers but much of the stuff on tap is pretty pedestrian.
