A Hudson River hot spot run by a key figure in the City Hall corruption scandal has filed for bankruptcy, saying it owes more than $600,000 in debt — including more than $116,000 in deposits shelled out by 12 patrons who booked weddings and other events there, court records show.

La Marina — an Upper Manhattan restaurant already facing closure following the suspension of its liquor license and the drug arrest of a manager — also owes $221,676 in back rent to the city Parks Department and hundreds of thousands of dollars in unpaid food, utility and other service bills, according to federal bankruptcy papers filed last month.

La Marina, located on city parkland in Inwood, has long been operated by a group headed by Fernando Mateo, a former taxi advocate and campaign fundraiser for Mayor Bill de Blasio. It has been shuttered since last November.

Mateo became enmeshed in pay-to-play allegations surrounding de Blasio after admitting to The Post in 2016 that he funneled $18,800 in “straw donations” to the mayor’s campaign.

In March 2017, both the feds and the Manhattan District Attorney’s Office said they wouldn’t file charges against de Blasio following lengthy investigations, and Mateo was never charged over his admissions.

“The city protected La Marina for years, and now Mateo and his partners are trying to rip off the Parks Department and beat customers out of money when they’re trying to celebrate their most joyous occasions,” said Geoffrey Croft of the government watchdog group NYC Park Advocates.

With the restaurant’s future in doubt, customers who scheduled events at La Marina have been left scrambling to recoup deposits as high as $22,444, which they claim the place is not returning.

They include three Manhattan couples planning weddings and a Manhattan mom who laid out $5,493 to reserve the joint for her daughter’s bat mitzvah.

Even City Hall staffers haven’t been spared.

Erik Cuello, a City Council aide earning $52,000 yearly, is trying to recoup a $12,412 deposit he and his fiancé laid out for their wedding, records show.

Cuello declined comment.

Both Mateo and business partner Josh Rosen claimed Saturday that Mateo is no longer “involved” with La Marina “in any way.”

But they declined to explain how a corporation based at Mateo’s Westchester address is still listed in recent court and state records as a partner in La Marina.

Instead, Rosen said in an email, “We expect to restructure the company and reopen in May as we normally do for the season.”

He also said La Marina would allow people who booked private events “out of their contracts if they so choose.”

Parks Department spokeswoman Crystal Howard denied that La Marina was previously able to skirt rules for years because of Mateo’s City Hall connections. She said, “All concessionaires are required to follow … city and state laws and are subject to oversight and scrutiny.”
