Holy Hamburger! World's first $1,768 burger

This may – or may not – be the world's most expensive burger.

But, geez Louise, would you want to pour ketchup on the $1,768 Glamburger?

The burger is made with 220 grams of Kobe Wagyu beef minced with 60 grams of New Zealand venison. It's made with Canadian lobster poached in Iranian saffron. It's got Beluga caviar and hickory smoked duck egg covered in an edible, gold leaf. Oh, did we forget to mention the champagne jus and grated white truffle?

Big Mac, it's not.

What it is: an outside-the-box publicity ploy by Groupon UK in celebration of its 5 millionth food and drink voucher. It's also a contest that Groupon is sponsoring. The winner not only gets to chow down on the burger, but the winner also is awarded round-trip cost of travel to the restaurant.

The burger was created by head chef Chris Large at the Honky Tonk restaurant in London.

One PR guru says the stunt may have some serious bite. "It's successful in a world in which the unique and bizarre often attract interest," says David Nevins, president of Nevins and Associates. "I don't think, however, that Groupon would sell too many of these burgers with their traditional 2 for 1 offering."

An outfit called Record Setters has certified it as The Most Expensive Burger in the World.

But, it appears Guinness World Records says otherwise. Way back in 2000, it says, a $5,000 burger was produced by Juicys Outlaw Grill in Corvallis, Ore, a food concession specialist, that created a burger that tipped the scales at more than 352.44 kilograms. (That's about 777 pounds). Juicys claims, on its website, that it will prepare and deliver the $5,000 burger to you with just 48 hours notice.

As for the Glamburger, well, it took three weeks to develop, says chef Large, who, in a statement, suggests, "The winner will certainly have a dinner to remember."

Hold the mayo.
