i tried the shrek shake and its not as good as a sharmrock shake, it's much sweeter and it has this brownish green color which is not really appetizing so I don't recommend looking inside the cup. Haven't tried the new mcflurry yet, but it looks better than the shake.
If you want a good mint shake, Chik Fil-A has a mint cookies & cream shake that is really good (their shakes in general are great).
Yeah, it's part of the Shrek promotion so they wanted a green shake to match Shrek's skin tone.
They should call it Shrek Drek.
Unlike the shamrock shake which has a creme de menthe taste, this has a spearmint taste ... like someone added a few drops of mouthwash to your vanilla shake.
That was the only saving grace ... it wasn't an overpowering mint taste. But it was really sweet (like Shrek?). On the first sip I immediately thought ... HFCS.
The Jack in the Box Andes mint shake is closer to the shamrock shake ... if only they didn't have those chocolate pieces in it.
