This place doesn’t let just any Yahoo in.

A posh Upper East Side restaurant’s door policy is so strict, staff are required to Google any guests they don’t recognize, and make sure they’re rich or famous enough to grace their dining room, according to employees and a document obtained by The Post.

Hostesses at Fleming by Le Bilboquet, a chic 20-seat eatery at Madison Avenue and 62nd Street, have to track emailed reservation requests, and then “pull up each unknown guest on google ” according to a page-long doc titled, “Fleming Hostess Reservation Protocol.”

The web-check policy was strictly to keep out the rifraff, workers there said Thursday.

“Yes, we Google people,” said one waiter, who asked to remain anonymous. “We want to keep the restaurant for special people only.”

The worker added: “There are more rich than famous people coming in but we get Robert De Niro, Paul McCartney, Ivanka Trump. We want to maintain a certain environment for our costumers, rich people, even if it means we’re slow.”

Any request for a reservation at the hot spot — which is a spin-off of legendary French eatery Le Bilboquet — needs to be discussed with “Alex,” the manager, say the written guidelines obtained by The Post.

A second employee, who works in the kitchen, said anyone who tries to make a reservation and isn’t acceptable after being Googled doesn’t get a call back.

Asked what made someone acceptable, the worker simply said: “Rich.”

A representative for Fleming, Josh Vlasto, admitted they do Google guests, but denied that they do it to deny seats to people who aren’t rich and famous.

“What the staff is claiming is absolutely not true and whoever said it is making it up,” he told The Post.

The eatery has some high-end owners. Billionaire Ronald Perelman and famed French restaurateur Philippe Delgrange opened the hot spot last year.

Other eateries in town have been known to internet-stalk customers in order to give them a more personalized dining experience.

High-end restaurant Eleven Madison Park has presented diners celebrating special occasions with mementos that draw from their own lives — leaving tables gobsmacked at the seemingly psychic souvenirs.

One Post reporter recently celebrating their birthday at the three-star Michelin restaurant was presented with a mock newspaper that included customized articles that included biographical details and were tailored to their interests.
