At Caffe Del Centro Antico (Via B. Croce, 15) they freeze espresso into ice flakes. They then add several teaspoons of sugar and put the concoction into a blender, mixing the ingredients on high for a good ten minutes. As the sugar and espresso chips whip up, airs fluffs the drink and turns it into a thick white color. The barista swirls small lines of caramel, chocolate or nut syrup inside the glass cup and then pours the liquid inside. The beverage tastes like a thick drinkable dessert. The sweetened grains of iced espresso have a sandy texture.
At the Neapolitan chain cafe, Il Caffe di Napoli (this one along Corso Umberto), they create the drink in a similar way, but call it the Grandfather Coffee or Caffe del Nonno:

Both these drinks, along with the Caffe Granita, are most commonly ordered during the hot summer months.
