This is an old topic but I found this info about this place:

During this era, many stores in Steubenville were fronts for mob rackets; bookmaking, numbers, pool, illegal drinking, and illegal gambling rackets. Steel mill workers from Steubenville and nearby Youngstown, Ohio would frequent these stores after their shifts, spending their meager paychecks for this entertainment. Craps and Barboot, a Greek dice game, were the games of choice at these places. The gambling halls would hire "mechanics", specialists in manipulating the dice and cheating, to police their craps games. The mechanic would ward off undesirable customers, break winning streaks of lucky customers, and hustle those with lots of money to lose.
