McDonald's Shamrock Shake Is Back—Here's How to Find One

While most people were still thinking about Valentine's Day, McDonald's quietly added a seasonal favorite to its menu in anticipation of St. Patrick's Day on March 17. The Shamrock Shake, a pale green, whipped cream-topped milkshake that tastes like mint, returned to McDonald's the week of February 11, Business Insider reports.

As was the case in past years, the shake is only available at select locations, but 2019 marks the first time that McDonald's has added a Shamrock Shake locator to its app. If you log in to the McDonald's app and enter your zip code, you'll be shown a map of the restaurants in your area that are selling the item.

Since it first appeared at McDonald's in the 1970s, the Shamrock Shake has grown into one of the chain's most successful special offerings. It's been sold under different names (like the St. Patrick's Day Green Milkshake), and it's inspired different promotional gimmicks (from Uncle O'Grimacey to a straw designed by aerospace engineers), but the minty milkshake itself hasn't changed much over the decades.

The Shamrock Shake comes in small ($2.19), medium ($2.59), and large ($2.99) sizes. It's now available at select McDonald's restaurants while supplies last through March 24.
