In-N-Out has a secret menu.
The menu at In-N-Out Burger hasn’t changed since the popular chain’s opening in 1948. But here’s a tasty morsel: the official menu displayed at the counter and posted at the drive-thru doesn’t tell the whole story. The restaurant chain also has a secret menu that offers specialties such as the Grilled Cheese, the 3×3 and other delectables. View the official secret menu here.
Not listed are the Neapolitan Milkshake, Fries Well Done and other foods of urban legend, which are ultra secret and ultra delicious. Shhh, don’t tell.
