I paid a fortune (for me) for a meal at a restaurant at the top of the John Hancock building with a window table. The views would of been stunning if it hadn't been thick cloud at the top and couldn't see a bloody thing. Went back the day after when it was clear and it was stunning views across the city and Lake Michigan.
Loved Chicago as a city. Much more than say New York which was just a bit too full on for me. Did a cubs game which was a great experience but i think that baseball is done this season for the cubs now.
