Their McCafé menu will feature the original Shamrock Shake, a Chocolate Shamrock Shake, a Shamrock Chocolate Chip Frappé, a Shamrock Hot Chocolate and a Shamrock Mocha.

The new Chocolate Shamrock Shake is just as it sounds: half a chocolate shake (on the bottom) and half a Shamrock Shake layered on top.

If the Chocolate Shamrock Shake sounds familiar, there's a reason. The drink has been a part of the chain's "secret menu," according to Consumerist . Before, customers could ask McDonald's workers to make a mint-chocolate version of the drink.

According to Brand Eating , McDonald's latest Shamrock beverages are already available in select locations. A wider roll-out is planned for Tuesday.
