You Can Now Make Reservations At Taco Bell's Test Kitchen (For 1 Day Only)

Calling all Tex-Mex lovers: National Taco Day is Oct. 4. To celebrate, Taco Bell is hosting fans for an exclusive dinner at their test kitchen in Irvine, California, where items like the Doritos Locos Taco and Quesalupa were born. The one-day-only experience will include a five-course meal created and plated by Taco Bell's top chefs. Reservations for the event can be made online through OpenTable.

Prior to its test kitchen feast, the chain will kick off "taco season" on Sept. 25 with a cutesy animated holiday special on Sept. 25. Glen and the Magic Taco will feature a cartoon character inspired by the company's founder Glen Bell. The short film will tell the tale of National Taco Day's origin according to Taco Bell.

"With calendars now awash in every manner of 'hashtag holiday,' we know that National Taco Day stands apart, and we want to help our fans embrace the true holiday spirit with an array of new traditions," said Marisa Thalberg, chief marketing officer at Taco Bell. "At this time I want to personally wish our fans a hearty 'Seasoned Beefings,' and a very happy National Taco Day to all."

And if that isn't enough for your taco-tainted soul, the fast-food giant is also releasing a boxed gift set equipped with four different Taco Bell tacos: Nacho Cheese, both Cool Ranch and Fiery Doritos Locos, and a crunchy taco "gift wrapped" in limited-edition packaging. The $5 box will only be available at participating restaurants on Oct. 4.
