so far i have tried Atkins Advantage Dark Chocolate Royale (160 cal, 2g carbs), Atkins Advantage Strawberry Shake (150 cal, 1g carbs), and Target's Market Pantry Ultra Weight Loss Shake in Creamy Milk Chocolate (170 cal, 24g carbs).... out of these 3 the Market Pantry by far is the best tasting and most filling.
