Grom is a gelateria with outlets all over Italy. Itīs often hyped and you even get some Grom gelato at the supermarket.
The gelato is pretty good and perhaps itīs the best gelato group in Italy. Nevertheless you canīt compare it to the top-Gelaterias from Dissapore list.
If you really like to waste your Money you can order a gelato-brioche. You get a small amount of gelato in a very cheap brioche (or something what looks roughly like it). This costs you around 5 Euros.....
