McDonald's Shamrock Shake: Elusive St. Patrick's-Themed Drink Returns [UPDATED]

McDonald's has succeeded in creating a cult following around at least two of its limited time offers: the McRib and the Shamrock Shake. The McRib returned nationally for three weeks in November. The Shamrock Shake always re-appears before St. Patrick's Day, but no one knows which locations will carry it. As of a few days ago, early reports have started to come in, declaring that the shake is back for 2012.

For those not familiar with the concoction, the Shamrock Shake is a minty vanilla milkshake that started being served in 1970. In the past few years, discussions about a recipe change have circulated, though the shake's in-demand status remains unthreatened.

For those seeking out the green beverage, the website keeps a running list of locations where the shake has been spotted. One can also lookup an address to find the closest Shamrock Shake.

UPDATE: The Shamrock Shake is now NATIONWIDE for the first time, reports CNN. It is currently available at every one of McDonald's 14,000 U.S. restaurants
