The Special K Granola Bars are quite tasty. They are .95 oz. which translates into a bar 3.25" long and just over 1" wide. They are on the small side, but are still slightly larger than Quaker Chewy Granola Bars. It may be their small size that accounts for the low calorie count because they taste really good, not at all like a diet granola bar.
They are considerably more expensive than Quaker chewy granola bars, however. A package of 30 costs $22 (.75 ea) while a package of 48 Quaker bars costs $16 (.35 ea). I do think the Special K bars taste a little better and are chewier.
