Shake Shack has a secret menu for Game of Thrones fans

But you better brush up on your Valyrian first

Shake Shack has a secret menu for Game of Thrones fans 1

The eighth and final season of Game of Throne is just days away, and Shake Shack is celebrating with a special offer for super fans. For a limited time, customers visiting the company’s Madison Square Park location will be able to order from a “secret” menu.

According to Delish, Shake Shack will briefly serve a new burger called the Dracarys Burger as well as a shake called the Dragonglass Shake. The $6.80 shake is “made with minted white chocolate custard, topped with ‘shards of Dragonglass’.” The $11 burger is “a double Monterey Jack cheeseburger topped with bacon and fiery ShackSauce.”

But before you go make a fool of yourself, you might want to brush up on your language skills. Delish says you’ll have to place your order in Valyrian, not English.
