Observe the employees.
Is the office full after 5 - 6 PM? Is everyone looking at the floor when the boss walk in? Is everyone's nails bitten to a bloody mess? Are there any female employees? Are the desk too clean and absent of personal items?

Pretty much, what is the density of the tech-aware crowd in that area?
Another good one: are the near by ash trays in use? If you're a non-smoker (like me) this is a red flag too.

Not sure if this a good enough criteria, sometimes you just dont find good female techies.
