The vestigial cabaret laws that the Giuliani administration used to crack down on quality of life violations may be overhauled by the Bloomberg administration:

City Hall is looking to eliminate — or at least loosen — the cumbersome cabaret license so more bars and businesses can allow patrons to let loose, the Daily News has learned.

“We either want to eliminate the license or establish a different license so that it would be less onerous for people to engage in dancing,” said a source close to the mayor.

The 82-year-old license “as it exists doesn’t offer a reasonable opportunity for New Yorkers to dance at clubs,” the City Hall source said.

The administration is in talks with the Consumer Affairs Department, which issues the licenses, and the NYPD, which enforces them, to make the change.

It is also considering forming a task force to examine the issue.

“I’d be tickled if we could get reform on this. New York City is the only city in the world where there is a law that makes dancing illegal,” said John McGarvey, a spokesman for Metropolis in Motion, a group fighting to change the law.

As the 1926 law stands, three or more people can’t dance unless a bar or restaurant has a cabaret license — even if music and liquor are allowed.

There are 181 licensed cabarets in New York, according to Consumer Affairs, and most are limited to techno-thumping clubs in Manhattan.

During former Mayor Rudy Giuliani’s quality-of-life campaign in 1997, police cracked down on venues without a cabaret license and the law became a quick way to shut down out-of-control nightclubs.
