World Most Expensive Hot Dog worth $69 in Guinness World Record Book

Does the world's most expensive hot dog cut the mustard?

Frankly, yes, declared a woman who forked over $69 for the winning wiener Friday.

"It was great. Great flavor," said tourist Trudy Tant, 49, who played a key role in helping a Manhattan restaurant savor another Guinness World Record.

Tant, of Rock Hill, S.C., said she was outside Serendipity 3 on E. 60th St. Friday morning - National Hot Dog Day - when owner Stephen Bruce asked her to spend her dough on the pricey frankfurter.

The publishing company worker said she relished the opportunity "to do something out of the ordinary."

The haute dog, prepared by head chef Joe Calderone, comes with truffle oil, a salted pretzel bed, truffle butter, duck foie gras, Dijon mustard, Vidalia onions and ketchup.

Tant paid for the foot-long with Guinness World Records official Kimberly Patrick looking on.

The restaurant racked up the priciest dog record right away; there was no previous titleholder, Patrick said.

Bruce said he chose to set a hot dog record because the frank is as American as apple pie.

The restaurant also holds the record for the most expensive ice-cream sundae - at a rich $1,000 - and the largest hot chocolate at 4 gallons.

"It's fun. I always want something bigger and better," Bruce said. "Who knows what we're gonna create next time?"
