Watch: Conan O'Brien Explores The 'Little Mexican Village' That Is Taco Bell Headquarters

This week on Conan, the flame-haired host took it upon himself to do something nice (but free) for one of his employees, IT "guru" Chris Hayes, who is a dedicated, almost daily patron of Taco Bell.

Conan decides on a trip to Taco Bell headquarters at 1 Glen Bell Way in Irvine, Calif., for a tour of the "tiny little Mexican village" that makes up the Doritos Locos Tacos enterprise.

Hayes, who qualifies for a special Taco Bell tour experience available only to the most devout "super-fans," is promptly given a Taco Bell face tattoo, then the tour begins.

In the Taco Bell museum portion of HQ, Conan and Chris get to see things like a brick from one of the first Taco Bell locations in San Bruno, Calif., and a timeline of the company's most important innovations (and mascots). The team also got to check out Taco Bell's Sensory Panel, a team of taste-testers whose job makes Chris rethink his entire career.
