East Williamsburg still has a small pocket which was traditionally Bonanno territory.
Same with Carroll Gardens/Redhook (Colombo) and Bensonhurst/Dyker/Gravesend (Gambino).
But yeah, these are just hold-outs.
But while there may not be new Italian families moving to Brooklyn, we still have all the great restaurants, pastry shops and specialty food stores! So I'm happy
