The pizza man has run out of dough.

Giorgio Kolaj, a co-founder of the 100-store Famous Famiglia pizza chain, who failed in his attempt to branch out into the more upscale restaurant business, has filed for Chapter 7 bankruptcy protection.

The bankruptcy petition, filed in White Plains, NY, comes as his former partner in the pricier eatery — the former Valentino’s on the Green in Bayside, NY — and the bank that lent the shuttered restaurant the cash sue Kolaj to collect a total of about $2 million they claim he owes them.

The ex-partner and the bank have been chasing Kolaj since Valentino’s, located on the New York City-owned Clearview Golf Course, closed in 2012.

The ex-partner, Atul Bhatara, claims Kolaj defrauded him out of a cool $1 million. The bank, Flushing Savings, is trying to collect on a $950,618 defaulted loan.

Among the other creditors is the New York’s Department of Parks & Recreation, Valentino’s landlord at the Clearview Golf course, owed $437,080, court papers show. Fishmonger M. Slavin & Sons is out $12,904.

“If he gets discharged from these debts then he can’t be held liable for them despite the pending litigation,” said bankruptcy lawyer Fred Stevens. “That’s why people file for bankruptcy.”

Kolaj, who runs Famous Famiglia with his two brothers, has liabilities of $3.2 million, according to court papers.

“As an immigrant family that built its success by being able to withstand the heat of a kitchen, we know that the restaurant business can be extremely tough. Today’s decision will help us get back to what we do best: working hard and doing right by our partners, our associates and our customers,” Kolaj told The Post.

In a previous interview, he said he lost “a tremendous amount of money” in the failed Valentino’s endeavor. “Vendors [are] still harassing me,” he said.
