Thinking about going to Chicago Gourmet (September 26 and 27), but scared off by the $150 ticket price? For today only, you can snag a one-day ticket to the second-annual food-centric fest (featuring a who's who of local, national and international chefs) for just $89 courtesy of Groupon. We're guessing the event has worked out many of the kinks (e.g. too much wine, not enough food) from last year, so this is a foodie deal worth investigating.
