Shamrock Shake is BACK at McDonald’s!

Grab one before St. Patrick's Day.

It's St. Patrick's Day season, which means that the Shamrock Shake is back at McDonald's for a limited time. This year, they actually have an app that makes it easier to find a location with the Shamrock Shake. Yep, there's an app for that.

The Shamrock Shake is only available for a limited time, after that, it will go back into hiding with the McRib.
