• Some downtown Newark business owners, who put in long work days in retail establishments, maintained accounts at the diner and would regularly stop off to dine and unwind on their way home after the close of their business day.
  
  
• Mahjong groups favored the Diner as a luncheon spot, using funds accumulated from their weekly games.
  
  
• The builder of the Diner, Sam Kullman, for many years dined at the Weequahic Diner with his family, not far from the family residence at 129 Keer Avenue, off Elizabeth Avenue.

Harold Kullman, present Kullman CEO and son of the founder, recalls that his father's diner food favorite was pot roast with noodles and gravy.
