Supersize me! Restaurant offers 338-pound burger

A US restaurant famous for cooking up giant hamburgers has outdone itself.

The Detroit News reports that Mallie's Sports Grill & Bar made a 338-pound (153-kilogram) "Absolutely Ridiculous Burger" on Thursday. A crowd gathered to salivate over the unveiling of the $2,000 menu item.

The sandwich packs 540,000 calories and takes 22 hours to cook. Manager Jason Jones says it comes with fries and a drink.

Over the years, Mallie's has drawn attention for cooking up monstrous burgers.
