At $100, could this be the world's most decadent hamburger?

A hundred bucks might buy you more than six dozen burgers from McDonald's, but the swanky Old Homestead Steakhouse will sell you one brawny beef sandwich for the same price.

Boca Raton Mayor Steven Abrams could barely speak between bites as he devoured the 20-ounce (567-gram), $100 (Ђ79.16) hamburger billed as the "beluga caviar of sandwiches."

"Heaven on a bun," restaurant owner Marc Sherry said.

The burger debuted Tuesday at the restaurant in the Boca Raton Resort and Club, where a membership costs $40,000 (Ђ31,665) and an additional $3,600 (Ђ2,850) a year.

"We've never had a hamburger on our menu here so we really wanted to go to the extreme," Sherry said, calling it "the most decadent burger in the world."

The mound of meat is comprised of beef from three continents, American prime beef, Japanese Kobe and Argentine cattle.

The bill for one burger, with garnishing that includes organic greens, exotic mushrooms and tomatoes, comes out to $124.50 (Ђ98.56) with tax and an 18 percent tip included. The restaurant will donate $10 (Ђ7.92) from each sale to the Make-A-Wish Foundation, which fulfills requests from terminally ill children, reports AP.
