It's worth visting here. Overal it's pretty cool. I have gone up here on a few occasions. It's obviously a different viewpoint than the Hancock bldg. I prefer going to the Hancock for this kind of thing. The Sears Tower's elevator is worth half the price of your admission, it's super fast so bring your chewing gum. Try to spend as much time as you can up there to get your moneys worth. Don't forget your camera.
