The lobby of the Atari headquarters at 14600 Winchester Blvd, Los Gatos, CA.
Atari moved to this location in 1973 and were there until 1976 when they relocated to Sunnyvale.
I work at the office that now stands on the same site. Sadly our lobby retains nothing of that pimp lair meets hobbit hole vibe.
