Do you know what a POPOS is? Privately-Owned, Public Open Space

If you work in downtown San Francisco, you may know of these spaces. I took a tour a couple years ago and it was fun. Amazing where you can go in privately owned buildings. Great places to eat lunch or just check out from the rat race.
