I could NEVER, EVER justify paying $69 for a hot dog.  Seems like a lot of money to spend on something that may or may not be made partially out of pig rectum.

But a restaurant in New York called Serendipity 3 thinks people are willing to open their wallets for just about anything . . . so they've unveiled the WORLD'S MOST EXPENSIVE HOT DOG.  It costs $69 . . . not including tax and tip.

This particular "Haute Dog" (as it's being marketed) is grilled in white truffle oil and is served on a chewy pretzel-bread bun (sort of like a cross between a soft pretzel and a baguette) that's toasted with white truffle butter. It's topped with foie gras pâté with black truffles. Condiments (served on the side) include Dijon mustard with black truffles, caramelized Vidalia onions and ketchup made with heirloom tomatoes (more like a tart tomato relish).

Serendipity 3 is known for these kinds of stunts.  They're also the home of the World's Most Expensive Ice Cream Sundae . . . which is covered in gold flakes, is served in a gold goblet, and sells for $25,000.
