No matter how many baseball games or summer barbecues you've attended, we're pretty sure you've never come across a hot dog quite like this one.

The Tokyo Dog food truck in Seattle, Washington, USA, recently unveiled what is now officially confirmed as the most expensive hot dog commercially available - retail price: a cool $169 (£101.69).

Dubbed the " Juuni Ban," this baby goes well beyond hot dog standards like mustard and relish, and far surpasses any chili or cheese.

In fact, the ingredients list for the footlong frank would make a Michelin-starred chef blush: the Juuni Ban contains smoked cheese bratwurst, butter Teriyaki grilled onions, Maitake mushrooms, Wagyu beef, foie gras, shaved black truffles, caviar and Japanese mayonnaise, all served up in a brioche bun.

As a requirement for the record, Tokyo Dog was required to sell at least one of the hot dogs in a legitimate business transaction. After announcing the dog, co-creaters Eugene Woo, Samson Kwong, and Rocky Yeh sold six Juuni Bans in one day, with California businessman Alan Chang as the first buyer, raising a total of $1,014. They, in turn, donated those profits to the American Red Cross.

A high price tag is great, but how did the dog actually go down?

Jean Nakayama, a chef at Seattle's Maneki served as one of the witnesses to the preparation and transactions.

"All ingredients were genuine and cooked to perfection," Nakayama said. "Presentation excellent. Total satisfaction!"

The Juuni Ban surpasses the "California Capitol City Dawg," which sold for $145.49 (GBP £93.39) at Capitol Dawg in Sacramento, California, USA, in May 2012. That 1 8-incher included French whole-grain mustard, garlic and herb mayo, sautéed shallots, mixed baby greens, applewood and cherry smoked uncured bacon, Swedish moose cheese, chopped tomato, sweetened dried cranberries, a basil olive oil/cranberry-pear-coconut balsamic vinaigrette and fresh ground pepper. It was served on a custom-made herb focaccia roll toasted in white truffle butter.

On-demand ordering for the Juuni Ban was provided as a one-off event earlier this year, but the frank remains on sale at Tokyo Dog for special events, requiring two weeks notice for any orders.

In the meantime, the truck will continue to tour the Seattle area this summer, offering menu stalwarts like the "Shibuya" (butter teriyaki grilled onions, teriyaki sauce, miso mayo, nori) and "Ginza" (plum sauce, butter teriyaki grilled onions, bonito flakes) dogs.

"We did this because we believe people are willing to pay for a top quality hot dog, and it was also a fun event for Seattle," Woo said. "We wanted to bring the record home."
