For the purposes of this discussion, let's assume that unflavored coffee with milk is kosher everywhere you go. (Related MY question)
Are Coolatas (from Dunkin Donuts) included in this?
A friend of mine went to a Dunkin Donuts and bought a Coolata, and a different friend asked him, with a look of amazement on his face, "You mean you can buy Coolata's at trief Dunkin Donuts!?"
Thought I'd ask if any kashrus organizations wrote anything on the topic.
