There are still a few clubs in brooklyn, queens, bronx, staten island and manhattan.
Mob life is far from a secret now a days so hanging at a club isnt a huge issue.
Its not like 20 guys with no job all hang at a club like they did back in the day.
Problem is more to do with the decline of the italian hood. Social clubs are part of our culture. Problem is opening a club and no one goes there. These were neighborhood hang outs back in the day where guys played cards, talked politics, and drank espresso.
The mob clubs are different diners, restaurants, and whatever. I see a few guys at the same place for a few weeks then they move to another place.
