You can so many sweet flavours - Chocolate Chip, Chocolate fudge, cookie dough, apple pie, white chocolate raspberry is my favorite and they all 5g of carbs or less per bar!
These things taste amazing, and are actually filling and also have roughly 20g of protein in them (they are meant for bodybuilders on low carb diets trying to get lean)
personally i love every flavour and buy these things 20 or 30 at a time lol
I get my Quest bars from either the local Sports Nutrition store, or online at www.bodybuilding.com
They aren't something that many people stumble upon because they are a 'bodybuilding supplement' type food designed for weightlifters and the like. But if you look around bodybuilding.com or sports nutrition places they often have many foods designed to low carb and taste great but usually in bar form lol
