Robigus, I live in Chicago. At one time LD lived here but now he just have property in the Chicagoland area. Anyways, I recommend Gino's East to get some Chicago Pie. I like the stuffed pizza not the pan stuff. I also like Stephani's.
Most good restaurants are nit by the airports. I like the dives in chi town. Some of the vest foods are from dives. You may want to stay in the airport since u only have 1.5 hours.
