Ha, I used to work inside this building in 2010.
Re stories: — the building has a well!! — apparently it is well stocked with enough food for a month for 20-30 ppl. I never independently verified this. — lots of tourists would walk up to the front entrance and try to poke around — yes no windows. My group tried to install screens in the office with feeds from cameras pointing outside - we were told it had 6 ft thick walls to withstand nuclear radiation
Ps I also worked in a phone exchange building. Cool thing was that there were half floors. 1, 1 1/2, 2, 2 1/2 etc. These floors were in fact half height like in the movie Being John Malkovich. Except there were no offices, they were used to route the huge cable trunks between floors and rooms.
These days with single fibers replacing thousands of cable pairs I'm sure they're a lot more roomy than they were back then.
You'd want to glance inside ex-AT&T 32 Ave of Americas for the full art deco.
That's a great story about the half floors!
That's how I ended up working there. 33T used to be packed full of gear but everything shrank so much that AT&T found themselves with dozens of empty floors. They didn't renew a lease on a big NJ lab I worked on, and a number of us ended up being able to choose commuting to NYC.
