The art museum is wonderful, don't miss the Thorne rooms, they are in the basement and my favorite exhibit - I've been known to go just to see them. And the science museum, and the natural history museum. Also Shed aquarium. Just walking along the lakeshore and the park there is really nice.
2 years ago I took my husband to Chicago when I was there for work and we went up to the Sears Tower at night, which I found more interesting than going during the day. It was also WAY less crowded.
If you are willing to go out into the suburbs, my husband liked
Cantigny in Wheaton, particularly the military museum, so much that we almost went back a second time.
