12. Doritos Locos Taco
Chain: Taco Bell
The champ is here. Indeed, the Doritos Locos Taco is Taco Bell's most popular product of all time, with sales of 100 million in 10 weeks alone. And its future looks even brighter with rumors of a Cool Ranch Locos Taco. You know you have a top-notch product on your hands when it rose above the Crunchwrap Supreme, which previously held the title of Taco Bell's most-sold item. When it came to challenging to the (former) champ, the Locos Taco took Omar Little's words to heart: When you come at the king, you best not miss.
