This is a gelato chain, and they even have locations in many other parts of Italy. Do not be turned off by this fact. Chain or not, they had the best gelato we had so far (and all the others were certainly good!). Grom's gelato is very creamy and delicious, but best of all, EVERYTHING in the shop is gluten free -- all the flavors, the biscotti, and even all the cones! A Celiac's dream! They also have very high quality standards, using all natural ingredients. Some gelato shops you pass by have heaping containers of brightly colored gelato, but even one of our tour guides pointed out that those aren't the best places. Clearly, they use artificial ingredients. She advised us to look for shops with artisan gelato, fewer flavors, natural colors, and covers for the gelato bins (since the best gelato shops don't use preservatives). All good advice! You can imagine how disappointed we will all be when returning to the U.S. -- even the best ice cream doesn't quite compare! And it's so nice that it's all so gluten-free friendly! We will be seeking Grom out in Florence and Venice so that we can try more of their flavors! This place is a must-visit when visiting Italy. Check out their many locations on their website.
