I picked up a small Affogato Dark Chocolate Ice Blended with cookies blended in for $2 during their recent open house. It's otherwise an 80-cent upcharge for the shot of espresso (may vary).
Because the shot is poured over the Ice Blended rather than mixed in before blending, it added an uneven dose of powerful coffee flavor. It dulled the sweetness and dark chocolate of the drink's normal flavor where encountered. As it mixed in, it evened out into an added edge to the dark chocolate.
Overall, both The Coffee Bean's Affogato option and cookies option were fairly enjoyable. The espresso shot is nice if you want some extra coffee flavor, while the cookies seem like they would work with most Ice Blended varieties, although the lack of texture was surprising.
