I'm doing a quick overnighter in Chicago this weekend. I get booted from my Airbnb at 11 am on Sunday and my flight home doesn't leave until 6 pm. I thought perhaps I could find a restaurant that serves a long, leisurely, tasting menu lunch or brunch to pass the time. Dress code can't be too stringent as the best I'll be able to do is a nice pair of shorts and a blouse. Price and cuisine flexible. Thanks in advance for your help!
