A US restaurant has beaten its record for the world's biggest burger with a whopping 15-pounder.

Denny's Beer Barrel Pub, in Clearfield, Pennsylvania, already had the title with a 6lb burger.

But owners thought a 15-pound burger would prove an even bigger attraction, reports the Pittsburgh Post-Gazette.

Diners who can finish the £25 burger in under five hours win £200, a T-shirt and have their name posted on the pub's wall of fame.

They also get the burger for free.

"Every restaurant needs a gimmick - ours is big burgers," said Dennis Liegey III, son of the restaurant's owner.

Visitors come from as far away as Australia and California just to see the 6-pounders and try to eat them.

The new burger, dubbed the Beer Barrel Belly Buster, is as big around as the inside of a car tyre.

It comes with a cup and half each of mayonnaise, mustard and ketchup, a head of lettuce, two onions, three tomatoes and 25 slices of cheese.
