I'm leaving for two years of volunteer service in Africa in less than a month. I've lived in Chicago for five years and have tried a wide range of restaurants (more low-end and ethnic than up-scale and pricey). I can't list them all but I'm curious what people would recommend as one not-to-be-missed Chicago restaurant/restaurant experience. I'd love to hear what you guys think so bring it on! NOTE: I'll eat anything.
