My husband and I will be in Chicago for the first time. Our hosts will be treating us to dinner (steakhouses... not my favorite) and our only free time will be lunch on Saturday. I'd like to find someplace downtown (we will be staying at The Drake) that has great food. It doesn't have to be fancy, just yummy. We like most ethnic foods. I'm really looking for a great bang for the buck kind of place. The kind of place that locals go to and is conveniently left off of the tourist maps! Any recommendations would be greatly appreciated.
