I never thought of this, but if you wanna eat deliciouse icecream Rome is the place to be!
There are several places to eat icecream with vegan options, mostly with soymilk.
But if you wanna taste something really special, you have to try “La Fatamorgana” !!!
They have tastes like apple/almond/cinnamon or chocolate/tobacco
on the picture of my last travel to Rome in june you see: Mojito/cherry , pineapple/ginger , mint/almondmilk/ginseng and chocolate/orange
