I went to Chicago last year 4th of July weekend. I stayed downtown walking distance to all the shopping and restaurants. Like others mentioned above, check out Giordanos pizza and Garrett's popcorn. My favorite spot is the Grand Lux. Make sure you check that out.
what size u need?...they had them at plus, premier, and refuge. I missed out on them too. They look so smooth in person. All they had was a 8, 8.5, 9 at Refugeif i recall correctly
