Taco Bell
Irvine, Calif.

Taco Bell’s Nacho Fries was the chain’s most successful product launch, the chain said. In three months, Taco Bell sold 53 million orders of Nacho Fries. The seasoned fries come with a side of nacho cheese dipping sauce. More ambitious guests could spring for the loaded varieties: the Nacho Fries Supreme and even bigger BellGrande, topped with seasoned beef, nacho cheese sauce, reduced-fat sour cream and tomatoes.
