I will always say yes to seeing a dessert menu at the end of a meal MAINLY because I have to do a once-over and make sure there isn't any hazelnut gelato listed. If you haven't had it before... that's a problem. Especially if you give any kind of a shit about Nutella, as most do.
Whole Foods has a gelato section and nine times out of ten, they have this flavour. I advise you to eat it if you have any kind of decency within you.
