The Shamrock Shake returns on Monday!
McDonald’s is also bringing back the Oreo Shamrock McFlurry. There’s also a mystery afoot and it has to do with the color code of the shake!
The eatery posted on socials "When the Shamrock Shake and Oreo Shamrock McFlurry make their return to U.S. menus later this month, show us how you're celebrating with #cbf2ac and #ShamrockShakeSZN. Starting Feb. 21, our Shamrock green hex code just might unlock another tasty secret. That is, if you know where to look. Be one of the first to figure out the mystery and you could get a little something special from us."
