I will be honest here, I didn't know what plantain was. So, I thought these were sweet potato chips. Plantain is a form of banana. With that said, I was kind of expecting a sweeter flavor (which I'm glad they weren't). The first taste is strange. It does have a hint of that banana flavor. It immediately diminishes with each chew. There is a slightly unpleasant after taste going on. It is gluten-free, so it's gentle on the stomach. And, extra bonus for those with IBS-C, these are rich in fiber! Overall, three stars out of five.
