John Hancock Building in Chicago, I consider the view better then the Sears Tower since it right next to the lake while the Sears Tower is more to the western part of DownTown Chicago
On the observation deck on a clear day you can see Canada across Lake Michagan. Also The Hancock Building has more Residential living areas.
Some floors are huge grocery stores , Malls, Health Clubs and even Bowling allys . It totally amasing
