A trademark treat from New York City's Coney Island will soon be available as a kosher snack at the touch of a button. Officials from both companies say Nathan's Famous hot dogs will be sold in vending machines run by Valley Cottage, New York-based Kosher Vending Industries LLC. Nathan's chief executive Eric Gatoff says the machines will help the company reach a growing audience of kosher customers. All Nathan's franks are beef, but relatively few are produced and served under a rabbi's oversight. They have been available only in certain restaurants. Kosher Vending Industries chief executive Alan Cohnen says the machines will get the dogs grilled and the buns warmed within 34 seconds. The company already has machines serving kosher items ranging from pizza to knishes.
