This year, there is no other flavor. In 2017, the restaurant had four Shamrock Shake flavors outside of the mint one: frappe, chocolate, hot chocolate and mocha. Instead, McDonald's is offering a Shamrock Shake Finder app on iOS and Android so customers can locate the popular dessert.

"Fans simply need to download the app and from there, locate participating restaurants locations, swap Shamrock Shake-themed stickers and raise a shake with friends to toast St. Patrick's Day," McDonald's said of the app in a Feb. 12 news release. "In addition to helping fans find the nearest Shamrock Shake, the app also features a brand new camera mode, featuring an augmented reality (AR) experience for iPhone X."

The Shamrock Shake was introduced in 1970 and is typically only available for a limited amount of time, disappearing around St. Patrick's Day.
