Lobster, foie gras, caviar and fresh truffle can be some of the most expensive ingredients chefs use. As of today, Columbus diners can get all of the above-and then some-all on one plate as Flip Side at Easton reveals a $350 burger.

Lobster, foie gras, caviar and fresh truffle can be some of the most expensive ingredients chefs use. As of today, Columbus diners can get all of the above-and then some-all on one plate as Flip Side at Easton reveals a $350 burger.

"It's something fun for the Columbus food scene," says Flip Side chef Max Rice III, who took nearly a year to perfect the burger he's calling the Queen Elizabeth. Though a pricey patty was the motivation for the burger's creation-he wanted to do something that would make a splash, and knew a mere $50 burger wouldn't cut it-it wasn't the driving force. It had to taste good, he says. "I started with flavors first because taste always comes first," Rice says. "Once I developed it, then it came down to this is what it's going to cost."

So, what exactly does $350 get you? Here's the breakdown of the Queen Elizabeth:

In the burger: A 12-ounce patty made with house-ground Ohio grass-fed rib eye and porterhouse, plus duck fat and foie gras.

On the burger: It's topped with lobster claws, one ounce of sturgeon caviar, 100 grams of edible gold flakes and sea urchin aioli.

On the side: Lobster fritters (made with tail and knuckle meat from the same 3- to 4- pound lobster whose claws top the burger) with squid ink remoulade and flying fish roe; and fries in duck fat with duck confit, smoked blueberry porter barbecue sauce and an entire Burgundy black truffle shaved over top.

What makes it work, Rice says, is the balance. "It's a lot of really bold flavors, but I've been able to take them down and tone them in a way they can work with each other," he says. "I think it's really, really delicious."

To get a bite of this dish, you'll have to preorder it at least 48 hours in advance. And as for the portion size, Rice estimates two could easily share the burger and sides. But if you're simply jonesing for a taste of it, the burger could satisfy three to four. The Queen Elizabeth hasn't even made the printed menu yet, and Rice says he's already got his first order request.
