In any event, I hold to the opinion that there is a general trend towards more assertive minty-ness in recent years. Way back when I remember the things just being sort of green with a pretty vanilla flavor profile. This year the Shamrock shake is of Creme de Menthe parfait like proportions. For the second year running there is no cherry included which pleases me (I hate cherries). I guess the only other thing of note this year was that there was a sort of pleasant green strata effect when viewing the shake from the side... You can kind of see it in the above pictures.
I have now documented 4 years of Shamrock Shakes... This sort of makes me examine what my life has become that I have wasted so many years documenting shitty novelty milk shakes on the internet. No matter, I regret nothing.
