Coke and a slice was their daily special.

A mobbed up Queens couple and their son were arrested Wednesday, accused of ​using their ​pizzeria and a produce business as mom​-​and​-​pop fronts for a cocaine operation that stretched from Corona to Costa Rica, according to a Brooklyn federal court complaint.

Gregorio and Ele​o​nora Gigliotti, the owners of Cucino a Modo Mio, on 108th St. in Corona, and their son, Angelo, 34, all face life in prison after a federal investigation blew the lid off of their secret stash, court papers state.

Using drug contacts in Costa Rica, the Gigliottis — whose restaurant name translates to “I Cook My Way” — orchestrated the shipment of cocaine in containers of yucca to a port in Delaware before having them trucked to their Bronx produce warehouse, court papers state.

Wiretaps of a phone line at their pizzeria revealed that the 58-year-old pizza patriarch — a reputed associate of Genovese capo Anthony Federicci ​— sent his wife to deliver a suitcase filled with $400,000 in cash to a drug dealer in Costa Rica last August, ​court ​papers state.

Over the past six months alone, the family received 55 kilos of coke worth roughly $2 million from the South American nation.

In addition to six guns, agents recovered $100,000 from the restaurant’s safe as well as $50,000 and another pistol in the Gigliottis home in Whitestone, court papers state. Appearing together in Brooklyn federal court Wednesday afternoon, the Gigliottis were held pending a bail package presentation.

The portly, bald and goateed Gregorio Gigliotti wore a white track top emblazoned with the word “Italia.”

Gregorio, who is originally from the southern Italian region of Calabria, was caught on the pizzeria wiretap talking to a contact in Costa Rica to arrange for his spouse’s drug deal, court papers state.

He later called her to instruct her to count out the cash that was to be handed over to the drug contact, according to the complaint. Ele​o​nora, 54, was generally tasked with stuffing cash in the luggage before drug deals, the ​feds allege.

When discussing drug transactions, Gregorio and his foreign contacts referred to cocaine as cassava and pineapples, papers state.

The feds also claim Gigliotti had a violent streak and threatened to re-enact grisly scenes from Martin Scorsese films if a certain debtor didn’t pay up.

“Do you remember the movie ‘Casino?” he asked his son in a recorded conversation. “Do you remember what happened to the two brothers? This is what I have to do to him.” Prosecutors contend that Gigliotti was referring to the brutal killing of Joe Pesci’s Nicky Santoro character and his brother Dom, who were beaten with baseball bats and then buried while still breathing in the Las Vegas desert.

The ring finally began to splinter last October after agents intercepted a 40-foot cargo container containing “cassava” sent from Costa Rica to a port in Delaware under the auspices of the family’s produce company. The shipment was found to contain 40 kilos of cocaine, court papers state.

The feds removed the cocaine from the shipment and left 1,200 cartons of yucca onboard before allowing its delivery to the warehouse.

“Things are bad,” Giggliotti told his Costa R​​ican contact about the missing blow on yet another incriminating wiretap, court papers state. “There is nothing of that,” he said, referring to the cocaine.

Undeterred, he continued to arrange for an additional shipment a week later before the feds swooped in on him, his wife and son Wednesday.

“Oh my God!” said one regular customer of the restaurant. “I’ve eaten there — mostly pizza. It’s a family owned business, you would never expect that. They’ve been here a little over a year and seemed very pleasant.”

The eatery was raided by roughly 30 agents during business hours Wednesday and closed up after they left, witnesses said.
