I know this is a bit old, but just leaving my feedback here, as I am still tasting the Pina Colada shakes
For me the problem here, as opposed to @KidCuisine, are the coconut flakes (I have been wondering what the heck those were until I read it here). I don't find the texture pleasant, they are too hard and noticeable.
Definitely a pity, because the flavor is great. Yes is subtle, but is there and very enjoyable. If this comes again as a limited edition without the flakes, I would run to for it!
