Since today is Saint Patrick's day, I couldn't help but recall the Shamrock Shake. Unlike the Lenten season, fast food restaurants have not (to my knowledge) made any effort to celebrate St. Pat's day... except for McDonald's with their Shamrock Shake.
But the green, mint flavored, 'triple thick' shake is getting harder to find. Posters at The Gothamist have had a hard time finding one, but some Chicagoist readers have been 'luckier,' they've even been advertised on the radio, evidently. Leave us a comment (below) if you find the Shamrock in your town.
The Shamrock Shake was such an icon as a seasonal promotional product at one time that it actually ranked its own mascot: Uncle O'Grimacey (pictured at left). There's more info on Uncle O'Grimacey on a site dedicated to bringing back the Shamrock Shake.
For some great Shamrock Shake humor, check out this satire from a 1997 Onion article: Sinn Fein Leaders Demand Year-Round Shamrock Shake Availability.
McDonald's only mention of the shake on their site says it is served during the green season in Ireland.
