O-Zones Pizza is located in the back of the Tower East, on the Ground Floor, to the left of Madisons, which was one of the Sun Parlors for the doctors and the visitors of patients. There is the main room, a hallway lined with tables, then a back room with a pool table.
It is unclear what this area used to be when it was a hospital.. some say caffeteria. It is clear, however, that despite rumors it was NOT the morgue, as there was a City morgue at the time.
