The actual building's windows are all painted over and that tree in the foreground does not exist. The freeway overpass pictured just across the street is a homeless encampment strewn with shopping carts, human feces, and needles. The city comes by about once a month to hose the sidewalk down with a noxious bleach solution.
btw, 888 Brannan is just around the corner from Zynga and Adobe.
