Hi! We are taking the train from St. Louis to Chicago the morning of 9/2. Staying @ Dewitt Place. We'd like to 'do' Chicago like a local. Not interested in High End Restaurants, but like good food. Would love some suggestions. We ant to see the sights....the Planetarium, the Aquarium, Navy Pier, Magnificent Mile.....we will not be available to sight see after about noon Friday and we leave Saturday. Any suggestions of what not to miss? And places to eat, good food and not spend a lot. We will not have a car, but we love to walk and I believe our hotel is located in an area that is conducive to walking. Thanks!!
