We are traveling to Chicago this Wednesday for a large family party with events all day Saturday and Sunday but will also need some good local reasonably priced restaurants to take a few people out for dinner Wed. Thurs. Fri. nights. We will have a car. Any suggestions for casual places not far from the Renaissance North Shore? Since we are apt to do this on a last minute basis, please recommend places where I can phone for a table reservation with only half an hour notice or where no reservations will be needed.
