The Greasy Spoon also had three Electro-Mechanical Pinball machines, and an original Space Invaders Deluxe (or Space Invaders Part II). They also had two generic looking cabinets, one with Crazy Kong (Yes, I said "Crazy Kong") & Ms. PAC-MAN with a generic "Lady Bug" Marquee.
The top floor was apartments, some rented out to vendors.
It's also quite possible that the restaurant was once a bootlegging house, as the county it was in is dry, and a rumored Prostitution ring was also going on.
