I am also from NYC. While Carroll Gardens does have young families moving into the neighborhood, there are an overwhelming number of Italian businesses that are there and have been there forever, a number of VERY old-school social clubs and patron saints in front of numerous buildings and brownstones.

Arthur Avenue has suffered much the same fate of Little Italy (its is just less touristy and has been encroached upon by non-Chinese ethnicities).

I cannot vouch for Staten Island other than Todt Hill and have spent little time in Bensonhurst so I welcome the corrections.

In Queens, Malba (Whitestone), Ozone Park and Howard Beach (which I missed) are also very Italian.
