Have you ever tried this delicacy from Ferrero? It's called Nutella&Go. In my opinion, is not that unusual. In a box we find only chocolate cream Nutella and a few brittle sticks. I bought Nutella&Go at Croatian gas station. If I remember correctly the price was about 14 kn (kuna). That is roughly 8 zloty. I havn't found any information about it on Polish websites. Probably it isn't available in Poland. And guess what? I don't recommend. It isn't cheap and in the middle is only 52 g of cream and 14 small sticks.
