As the founding family of Orange Tree Hot Dogs, the Koppenbergers have carefully guarded their secret recipes since opening the first location in 1968. The "dash of magic" outlined in those recipes is central to the coleslaw that tops their most popular hot dog, the aptly named slaw dog, or the savory sauce that blankets the onion-sauce dog. The Koppenbergers' menu also features their popular Orange Frost drink—made with orange juice, orange syrup, and ice—which serves as both a refreshing treat and an extinguisher for mustaches that catch fire.
