A ​popular Portuguese restaurant secretly served as ​the base of ​a $400 million money-laundering operation tied to the Genovese organized crime family, New Jersey officials charged Tuesday.

The PortuCale Restaurant & Bar in Newark’s Ironbound section allegedly let customers cash hefty checks without requiring identification or filing currency transaction reports mandated by the feds, allowing the customers to hide income or get money for “under-the-table” payrolls.

Owner Abel Rodriguez — whose eatery boasts ​four stars ​on the web rating site Yelp — charged fees of up to 3 percent for the illegal service, which generated more than $9 million in profits over four years, according to acting New Jersey Attorney General John Hoffman.

Rodriguez kept 1 percent and turned the rest over to Domenick Pucillo, who runs the Tri-State Check Cashing business and financ​​ed the scheme, according to Hoffman.

Pucillo gave one-quarter of his profits to another man, Manuel Rodriguez, who passed a portion “up the chain” to reputed Genovese soldier Vito Alberti and reputed Genovese capo Charles “Chuckie” Tuzzo, Hoffman said.

Tuzzo, 80, of Bayside, ​Queens, ​and the other men were among 11 defendants charged Tuesday with a ​slew of crimes ​connected to money laundering and other mob scams, including loansharking, illegal sports betting and scoring no-show jobs at a trucking company that hauls imported Nissan autos from Port Newark.

The defendants include two women — Flor Mirand​​a and Jennifer Mann — who worked for Pucillo’s Tri-State Check Cashing company as an office manager and compliance officer, respectively.

Miranda allegedly collected loansharking payments and kept track of illegal operations at Tri-State, while Mann allegedly issued hundreds of false currency transaction reports to cover up the check-cashing scheme and tax evasion at PortuCale.
