I admit this is a semi-inside joke. But don't go to the 20th floor. I swear its the rejected EVERYTHING from all other floors. I've worked on a number of floors in this building from the 2 years I've been here and 20th is the worst. Crayon markings on the wall, broken chairs, broken desks, outlets that don't work. I just don't get it. Seriously though overall the building is in great shape (other floors) with a very nice trading floor but its just awful how bad they let some floors go. Interesting fact. Its the building that Chandler (from Friends) works in throughout the series.

"The large red sculpture of the digit 9 in front of the building was included in the project as a response to the complaints that the building's sloping reflecting walls revealed unappealing sides of the neighboring historic buildings that were previously obscured. The brightly colored sculpture was to distract the eyes of passersby from noticing these walls." read more
