Yeah, not that one.
I had already guessed that...as the one in Orange County would not give you food unless it was after a donation.....and it does not have cement walls....
But I was told by Daniel, if you like cement walls and free meals....and you desire to stick to the Oakland area, you should try the Alameda County Jail...they say the menu is powdered eggs for breakfast, sack lunch, and then at dinner time pressed tofu in the shape of lamb chops with soy sauce on the side.....lol!
