ChocoPerfection 1.8 oz. Sugar Free Chocolate Bars - No Maltitol

twelve thumbs up for the dark chocolate.

They carry these at my local health food store. Though they are less expensive to order by the case from netrition.

I haven't tried the milk chocolate. But the dark chocolate is really good IMHO.
It doesn't taste like fake chocolate or have a wierd after taste.
The bar is 2 carbs for the whole thing. Not bad, since one square is way more than enough to save me and give me a treat.
