Taxi Service.

Watch as Angie Harmon Introduces Conan O’Brien To The Greatness of Mi Cocina’s Mambo Taxi.

Dallas is known for a few things when it comes to boozing. The margarita, after all, was invented here. So, too, was the frozen margarita.

But one of the best-kept drunken secrets of the city, no doubt, is the Dallas-based restaurant chain Mi Cocina‘s take on the frozen margarita, the Mambo Taxi, which swaps out triple sec and lime juice for the joint’s in-house sangria.

That drink gets a little less secretive tonight on Conan, though, as proud Dallas daughter Angie Harmon pops up as a guest to promote her TNT drama Rizzoli & Isles and, in anticipation of Conan‘s upcoming trip to Dallas, introduces namesake host Conan O’Brien, his sidekick Andy Richter and fellow guest Jeff Goldblum to the greatness that is the drink.

Warns Harmon of the drink’s potency before everyone indulges: “You can only have three of them.”

Says O’Brien of the drink after the fact: “That’s fantastic! That is really good!”

Adds Goldblum: “Well, it’s delicious. And it packs a punch.”

The show airs tonight at 10 p.m., but thanks to the Team Coco team, who just passed the clip along our way, you can check it out here, right now, below.
