Donald Trump was back at ‘21’ on Monday night after he’d ditched his press pool to dine at the iconic eatery last month.

But a regular said Trump passed up his regular table for the private Remington Room.

“He was accompanied by dozens of police officers and Secret Service,” said a source, “as well as [wife] Melania, [daughter] Ivanka, son-in-law Jared [Kushner] and [sons] Donald Jr. and Eric.”

Diners applauded Trump’s entrance, and he shook hands with guests and posed for pics. The president-elect also popped into another private event at ‘21,’ which we hear was “all real estate guys.”

Earlier in the day, members of the Manning family NFL quarterback dynasty — dad Archie and sons Peyton and Eli Manning — hosted their annual holiday lunch at ‘21’ for about 30 guests, we hear. (The eatery has one of Archie’s old helmets hanging from its ceiling.)

Since opening in its current location in 1930, every president’s dined at ‘21,’ except Barack Obama. Said a source of Trump’s latest visit, “they have the ability to handle Secret Service from years of experience.”
