By now it's pretty much common knowledge that Shake Shack has a secret menu, but for a limited time, customers at the original Shake Shack location in Madison Square Park will be able to order two new items. However, unlike the original secret menu, these two items require a little bit more effort. In partnership with HBO ahead of the Season 8 premiere of Game of Thrones, Shake Shack is offering an exclusive burger and milkshake that you'll need to speak in Valyrian to order.
To those not in the know, Valyrian is a fictional language created by David J. Peterson. The newly launched menu features the Dracarys Burger and the Dragonglass milkshake, but to order either of them you'll have to ask for the "Drakaro Parkliapos" for the burger, and "Zirtom Perzomy Rholītsos" for the shake. Unfortunately the items won't be available at any other Shake Shack location, and the burger will only be served until April 21 while the milkshake says farewell on May 19.
The Dracarys Burger is a spicy one featuring Monterey Jack cheese and bacon, while the shake is white chcolate mint topped with black toffee.
The final season of Game of Thrones premieres on April 14.
