Didn’t get tickets to the Great American Beer Festival? Not to worry. You can still get a buzz going at Old Chicago restaurants during their Gold Medal Mini Tour through Aug. 19. There are eight golden-hued beers (in honor of the 2012 Olympics game medals) to enjoy on your way to winning a limited edition T-shirt. Of particular interest to beer fans is the Wheel Sucker Wheat by Avery Brewing Company and Ska Brewing Co., which is exclusive at the eatery while supplies last.
