I'm not sure if anyone has said so yet, but the Atkins Advantage shakes are veeeery good.
I've had vanilla, which is better on the warmer side, strawberry which is not good at all, Caramel latte, that one is pretty good, good to have in the AM instead of coffee, its made with real coffee and actually tastes like a lite caramel latte, and the milk chocolate is the absolute best! I don't like chocolate drinks but it tastes like a chocolate milkshake, except not as thick.
All shakes are 15g Protein and 1g sugar. So worth it!
