You can purchase tickets to the Skydeck. It is 103 stories up. You can walk out onto transparent, plastic and glass walkways that allow you to see all the way down to the ground below. It is a bit scary but cool. They have a gift shop and some of the best views of Chicago.
When you still up in 103 floor yes can see all 360° dawn that is espectacular,yes can buy souvenir
One note on the skydeck, the wait time to go up exceeded 4 hours both times I tried to go. They are negligent in how many tickets they sell and the ensuing line.
