I'm always surprised I've never heard anything about the similar room at Facebook's old California ave. hq. There was a secret door in the basement to a small "situation room" type place.
I remember seeing a photo of it once when they were about to launch a new product. I can't seem to find it but I think Robert Scoble took it so try his Flickr account.
I wish. The story with me was that I had already quit to go to another startup. I knew there was a rumor about a secret room so I decided to go look for it. I found it and it was pretty awesome. Maybe 10 Aeron chairs around a glass and metal table with 3-4 50" LED-TVs on the wall. Wish I had taken a picture but I was already pretty nervous I was somewhere I wasn't supposed to be.
