We have family in Mestre,stay here often. It's a place lots of tourists stay since it's cheaper then Venice and easy to get there.
This trip I decided to get more serious about local Gelaterias, and though there were several good choices in Mestre, this one was very close to where we stay.
I went two evenings and was very pleased. Very delicious and artisanal gelato. Most of the classic flavors and reasonably priced though servings were a bit more modest then many other places I've been in Italy. Highly recommend!
