If your booked one of their tours, you get in at a discounted price! The space has some interesting exhibit on Chicago and skyscrapers around the world. Nice gift shop if you are an architecture buff! I took their architecture cruise and it is very well organized and the narration from our guide was so so good. It only she was knowledgeable but also funny as hell! Thoroughly enjoyed it!
