This transition is a microcosm of the demographic shift throughout the rest of the U.S., according to this piece from The New York Times.
"As the ranks of Mexicans in New York have exploded in recent decades, their impact on neighborhoods where they have settled in the largest numbers has been well documented, like East Harlem, Mott Haven in the South Bronx, and Sunset Park in Brooklyn.
But Belmont offers a glimpse of how Mexicans are gaining a foothold in other parts of the city that are less clearly labeled and where their numbers are far smaller. Slowly and quietly, the neighborhood's Mexican population appears to have reached the cusp of a breakthrough, injecting new life into the area, placing demands on its services and challenging the old ways."

Arthur Avenue
This is not "New York's historically Italian Little Italy." That designation belongs to the historical enclave in Lower Manhattan (which has now been mostly subsumed in the growth of Chinatown.)
New Yorkers typically refer to the area discussed in this article as "Arthur Avenue."
What about the Albanians?
The article mentions Albanians briefly, but neglects to say that not only are there a few Albanian restaurants on Arthur Avenue, but that some of the Italian restaurants are run by Albanians as well.
Most of the Italians are long gone; the Mexicans are displacing Albanians and Puerto Ricans.
