There is a little place just down the street from us (and another one in the neighborhood next to us) that sells authentic Italian gelato. I don't remember if we actually looked it up or just stumbled into it last summer.
But either way : we love it & make a point to go after dinner every couple weeks.
My favorite flavor is pistachio, but really, you can't go wrong with any of them and you get unlimited taste tests before you make your pick. They also serve coffee, pastries and sandwiches. But on the rare occasion I'm there midday, I go with iced tea. I don't know what they do to it, but it's fantastic.
Be sure to stop by if you're in town.
