The Real Burger King

(CBS/AP)  A Pennsylvania restaurant that earlier this year lost its crown as home of the world's biggest hamburger has reclaimed it, offering one that weighs a whopping 15 pounds.

Dubbed the Beer Barrel Belly Buster, the burger comes with 10.5 pounds of ground beef, 25 slices of cheese, a head of lettuce, three tomatoes, two onions, a cup-and-a-half each of mayonnaise, relish, ketchup, mustard and banana peppers, and a 36-ounce bun. It costs $35.

"It can feed a family of 10," said Denny Liegey Sr., owner of Denny's Beer Barrel Pub.

The pub previously offered an 11 pound burger, with 6 pounds of meat and 5 pounds of toppings.

In February, a 100-pound female college student became the first to eat the burger within the three-hour time limit. Kate Stelnick, of Princeton, N.J., was awarded a special certificate, a T-shirt and other prizes, and Liegey Sr. picked up the $23.95 tab for the burger.

A month later, the Clinton Station Diner in Clinton, New Jersey, introduced a 12.5-pound burger, dubbed "Zeus." So Liegey Sr. responded, and the Belly Buster was born.

Over the weekend, four men took the Belly Buster challenge, but couldn't get through the entire burger. They opted for doggie bags, instead.

"It's a little too much for me to handle," said Steve Hepburn. "It's like trying to eat half a cow."

According to the Guinness Book of World Records, the largest burger ever was created in 1999 by Hi-Line promotions. It was 6,040 pounds, and 24 feet in diameter. But that was a one-shot deal.

On The Early Show Wednesday, Beer Barrel Belly Buster in-hand, Denny Liegey Jr. told co-anchor Harry Smith this burger has been certified by Guinness as the biggest restaurant burger.

He says his family's pub started with a two-pound burger in 1991, and it "just kind of evolved from there."

The 10.5 pound (after-cooking) patty alone "could probably serve a family of ten," he added.
