If you're out in the suburbs at all you can knock off several in one day. Emett's Ale House in Downer's Grove, Taylor Brewing in Lombard, Rock Bottom also in Lombard, Lunar Brewing in Villa Park, and Two Brothers in Warrenville. They're all a pretty short ride from each other. In fact Rock Bottom is just across a mall parking lot from Taylor Brewing.
This sounds like a good road trip. Several places all in close proximity.
