So in your experience, how many Porteņos actually speak Italian well enough for me to get by? I ask because it'll be my first trip to that magnificent city and all I know are English (100%) French (75%) and Italian (40%). I guess I could add that I know a few words of Spanish and German but not enough to be of much use.

The real question here: will my Italian be of any use whatever? I like to use it when I can--so far, only in Italy
