Rather than recommending a brew pub I would recommend Hopleaf - they have an incredible selection of beer, great atmosphere and good food (a little pricey on the food side). Here is the link...http://www.hopleaf.com/

To get there, take the Red Line (Howard) to Berwyn. Walk west to Clark and go two blocks south. Or take the 147 bus from Michigan Av to Foster/Sheridan and walk west on Sheridan 4 blocks to Foster and take a left (south).
