Grom gelato has three locations in New York city (one location in Midtown another at 233 Bleecker street in Greenwich village and the third 76th and Broadway on the West side). We have been to all three and enjoyed every second of our visits! The chocolate fondante is totally divine! The gluten free boy ate a combination of lemon sorbet with chocolate fondante.
The flavors not suitable for celiacs (or wheat allergies) are clearly marked with an appropriate wheat stalk picture 🙂
Grom also has stores in Rome and Florence–at all locations items containing gluten are clearly marked–
