I wonder how these guys came up with the worlds most expensive hot dog without using onions, chili, mustard, sweet or dill relish or any of the recognizable condiments that we Americans are familiar with.  This hot dog looks more like some kind of hot dog looking desert, but no, what you are about to view is the building of the worlds most expensive hot dog.  Most of the ingredients I have heard about on Food TV but never actually tasted or touched.  Truffle oil, truffles, caviar are some of the toppers just for starters.  I really don't know if I could get passed the smell just to get to the foot long all beef dog that sets in the middle.  Now THAT is something I recognize.  Lady's and Gents, the Worlds Most Expensive Hot Dog.
