I had a gelato cone in Florence in August that almost made me swear off of gelato. Not because it was bad, but because it was so good that nothing else could possible match it.
Hell, I almost swore off of food for the same reason. "Why bother eating again? This is as good as it will get."
The place was on the southwest corner of the road that runs south of the river and a roads that runs over one of the bridges. It had a gourmet food section as well; that part of the shop had "Emporia" in the title.
The cone was coconut on the bottom, dark chocolate on top. Like a Mounds bar.
I had some really good pistachio too. I don't recall any being bright green. The best I had in a dish with a scoop of an unusual mix flavor . . . ginger hazelnut? Something like that. It was great too.
