This magnificent viewpoint is on the 94th floor of Hancock Tower. Although it seems very high, the ascent from the basement only takes half a minute. Once you get to the top, you get a new perspective of Chicago. The views, obviously, are amazing. The advantage over Sears Tower is that it is in a more central location with a direct view over Lake Michigan. If you have only budgeted for one viewpoint, take this one. The visit includes the rental of a hearing aid to understanding what you are seeing and a drink at the bar. After all the bells and whistles, you will spend an hour there, so I believe that is a worthwhile investment.
