AlexB,

Agreed -- the Marriot Marquis in ATL is something special; and the breath-taking view from the top down on the interior is spectacular!

Several further examples in Chicago fit your request.

1. Try the Fine Arts Bldg. @ 418 S. Michigan for an Antique elevator ride (complete with operator).

2. Obviously, the Sears Tower elevator is really something (ears popping all the way up as you try and catch your breath).

3a. Try the Water Tower Place elevator (across from the Hancock Bldg.) for a cool and quick all-glass lift (make sure it's the express elevator to the top of the mall).

3b. Try the State of Illinois Bldg. elevators over-looking the huge glass lobby and 200-foot entry way. (Yes, it's that large glass building -- designed by Helmut Jahn -- that looks like a spaceship crashed in the loop. Just hop off the L at Clark and Lake and you're there...)

Enjoy!
