I don't like things in chocolate. They make chocolate worse. What's the point? But I do like chocolate in things. Because it makes things better.
So, if you are going to do something "healthy" like have a granola bar (and for the record, the Nature Valley granola bars are way better than the mushy alternatives), you might as well throw some chocolate chips in there.
Bottom Line: Why eat a granola bar without chocolate chips when you can eat one with chocolate chips?
