The Double Decker Taco is a hybrid taco offered at most Taco Bell locations, consisting of a soft flour tortilla wrapped around a traditional crunchy taco with a layer of refried beans serving as a mortar between the two tortillas. After the advent of the Why Pay More! Value Menu, the double deck taco is no longer a sub-$1 item. Although the Why Pay More! Value Menu offers the taco as part of their $2 Meal Deals.
The Double Decker Taco was introduced as a limited-run promotional item in 1995 and was advertised in a series of commercials featuring NBA basketball stars Shaquille O'Neal and Hakeem Olajuwan, before becoming a permanent menu item. The Double Decker Taco joined the regular menu items in June 2006. Research historians maintain the orginal Doulble Decker idea originated at a small Taco Bell in Kent, Ohio. However, instead of beans, nacho cheese was used to keep the hard and soft shells together. One worker who was an employee during that time period stated, "We could never decide which shell to have, hard or soft...so we created this concotion of deliciousness." After a visit from a member of Taco Bell's corporate office, it showed up on Taco Bell menus less than 6 months later.
