There were once at least three Jahn's ice cream parlors in Queens. I believe the one in Richmond Hill opened first, then one in Jackson Heights, and finally one in Rego Park, or maybe it was in Forest Hills. As far as I know, only the Jahn's in Jackson Heights is still open. The Kitchen Sink is a Jahn's sundae with twelve scoops of ice cream plus various topings, including syrups, whipped cream, sprinkles, nuts, and cherries. I really can't imagine anyone other than a sumo wrestler, King Farouk, or Orson Wells really eating one by himself.
