I picked one up for $2.59.
The color was a deep, somewhat rose, shade of pink and made me wonder how much food coloring I was drinking. No more than a slice of red velvet cake I suppose.
Beyond the thick texture, there's enough bits of Oreos that you get a few granules with every sip but not so much that it feels grainy.
Taste-wise, it's mostly like an Oreo or cookies and cream shake but with a noticeable cream cheese flavor but no chocolate flavor beyond the Oreos. The cream cheese flavor complemented the cookies and cream very well.
