Another iconic building in Atlanta (at least for people from there) is the Westin. The Westin is one of the tallest building in Atlanta and is famous for having a rotating restaurant on the top floor called The Sun Dial. One of the things I remember best about the Westin was when an EF2 tornado hit downtown Atlanta and blew out a large number of glass panels.
I remember it taking forever for those glass panels to be replaced and they eventually had to replace all of them due to the specialized nature of the glass. Gotta go eat at The Sun Dial sometime.
