There are gelaterias all over the Bay Area and most of ’em sell sorbetto as well as gelato. I realize there’s a subtle difference between sorbetto and a true water ice, but around here they often serve the sorbetto is "squeezy cups" too and it’s awfully good. The best place to get it used to be on Columbus Ave. in North Beach but I forget the name and don’t know if it’s still there. Gelato Classico and Ciao Bella are two chains around here that have it. And then, since Chinese is really the largest local ethnic group (larger than us "Euros"), we have "Marco Polo Italian Ice Cream–Italian Ice Cream with an Asian Flair".
I also recall Italian ice was common in Baltimore from when I was in school there.
