I just finished the PB&C shake from the cold stone creamery.
Wasn't bad. Tasted pretty good. Was rich and creamy.
I took it home and melted it so that I could actually drink it. Don't really like those shakes so thick that you waste more calories trying to drink the damn thing than you get out of it

Overall nothing special. From what I saw when they mixed it up, it's just ice cream peanut butter and milk. You could probably make it at home and not spend the 5 bucks on it.
I kinda thought that it would be bigger for the calories and hubbub.
Next round is to try that smoothie!
