Serendipity 3 in New York City is serving a $69 hot dog, or "haute dog"...

Serendipity 3 grills the all-beef foot-long sausage in white truffle oil, places it on a pretzel roll toasted with white truffle butter, and tops the haute dog with duck foie gras, black truffles, caramelized Vidalia onions, Dijon mustard and heirloom tomato ketchup. 

Guinness World Records has certified the haute dog as the most expensive of its kind in the world.

I don't care how good it might be...$69 should buy you 69 hot dogs.
