To make this question less localized:
"If one is in New York City, is it possible to tour the Stack Exchange Headquarters?"
Original Question (7/14/2012):
I live in Los Angeles (Orange County actually) and this is my first time in New York City! My girlfriend and I are staying in a friends apartment on the upper east side of Manhattan; we have 7 day unlimited subway passes and are doing all the touristy stuff. I thought it would be fun one afternoon to come say hi to the people that run my favorite network of sites. My girlfriend knows Stack Overflow as "that site I am always on" and when I mentioned the idea to her she also thought it would be fun to visit the SE HQ.
So, can my girlfriend and I come tour the Stack Exchange office(s) sometime in the next few days while we are here in NYC?
(We are here until Wednesday (7/18) morning, so Monday or Tuesday would be perfect [assuming the offices are closed on weekends])
