Ditka’s in Oakbrook is across the street from the mall.  It is an extremely busy place and reservations are a very good idea.  It is basically a steak place and has a great lively atmosphere.  The wait staff is friendly and helpful.  There is free valet parking.  The food is very good.  The steaks are of high quality and the sides are very interesting.  However it is very pricey so beware.  If it is a special occasion, a business situation and someone else is buying or cost is not a concern you might give it a try.
