Will be attending a wedding in Oak Brook over Memorial Day - we are flying in Friday and out on Tues pm - would love some recs. We have never been to Chicago before and want to know where the best Chicago foods are located. Since we are from Boston, we have never had deep dish pizza and want to try the "best." Not sure what other foods would be typical "Chicago" foods and would love to try them all. We plan to spend time near waterfront and in downtown Chicago it'self . We are staying out near Oak Brook.
