Four Texans are heading to Chicago for a family wedding in early September. We are staying on E. Walton, which I believe is in the Magnificent Mile area. We are up for anything, but are looking for things that Chicago is known for, which I think is Italian beef (?), pizza, hot dogs and Greek food (?). Dinner on Friday and Saturday are covered with the wedding. I believe the reception is at Spiaggia's. Looking for fun, laid back places. Also need a great brunch on Sunday before we hit the airport.
