There are more cops and politicians eating at Bamonte's than wiseguys. When Ray Kelly was Commissioner he was there twice a week. Giuliani was there all the time, too.

As far as what happened to the Mafia in Wiliamsburg, it's the same thing that happened to the Mafia in the rest of the urban boroughs. Gentrification, assimilation and White Flight. There are still pockets of Italians left in urban Queens, Brooklyn and the Bronx. But no strongholds. Forget about Manhattan. And Staten Island, while largely Italian, is too suburban to count. It's more like North Jersey than the rest of the city.
