875 North Michigan Avenue

"There are two tall buildings that you can pay to go up and see the view. The Willis Tower (formerly the Sear’s Tower) is the most famous, or the John Hancock Building, which is located on Michigan Avenue. My tip: take the elevator up to the Signature Room on the 95th Floor at the John Hancock and get a drink with a view instead of paying to go to the observatory. Perfect after shopping and to warm up with a hot cocoa or coffee. "
