Here it is, the star of the Burger King show, the signature Whopper Sandwich. This quarter-pound giant has carried the company since 1957 and has inspired a multitude of spin-offs from competitors trying to keep up with the Whoppers blazing popularity. The burger is so iconic that BK even bills itself as The Home of the Whopper. And biting into one, its easy to see why this burger rose to such prominence. The flame-grilled beef alone sets the Whopper apart from the competition, but then its juicy, meaty flavor is contrasted with tomato, pickle, lettuce and onion to deliver an extraordinary burger experience. The Whopper is truly the king of burgers.
