Need I say more? The Shamrock Shake is back at McDonald's.
Curiously, this past year here in Southern California, McDonald's did not have a holiday shake. Jack In The Box had a holiday shake that was minty and good -- so I was visiting Jack for my holiday shake fix.
Only during Shamrock Shake days do I consider McDonald's to have the best milkshake. Otherwise the title of the Best Milkshake goes to... Arby's for the Jamocha shake. And when I order a Jamocha shake at Arby's I always ask for extra Jamocha.
