Best gelaterias in Italy

After a week of dedicated taste testing with my family, I've found the following as most representative of delicious gelato (all also have dairy free gelato and gluten free cones).
  1. 1. Rome - Cremeria Monteforte, near Pantheon
  2. 2. Viareggio - Laboratorio de Gelato
  3. 3. San Gimignano - Gelateria Dondoli
  4. 4. Castellina - Antica Delizia
  5. 5. Florence - Festival del Gelato
