The boozer is located in Marylebone, Central London

Princess Beatrice has a special link to a pub in London, regularly visiting the establishment.

The Hart in Marylebone is often used by the royals, including Beatrice’s sister, Princess Eugenie.

Following the christening of Athena Elizabeth Rose Mapelli Mozzi at St James’s Palace, Beatrice and Edoardo Mapelli Mozzi enjoyed a long lunch at the pub.

They were joined by several other guests, including Eugenie and her husband, Jack Brooksbank, James Blunt, Princess Nina and Prince Philippos of Greece.

The royal-studded luncheon took place in the upstairs of the private venue, with guests having to walk three flights of stairs.

Known as The Den on the top floor of the pub, the area is described as the “perfect setting for group dining and private events”.

The Den includes a cocktail bar and a featured fireplace.

The establishment’s dining room contains “bespoke British lighting and gas fires”, though it can only be hired jointly with The Den.

Next to it is The Snug, another private area, slightly more of an “intimate space” which can accommodate up to 16 guests for a meal.

At the back end of last year, after Beatrice and Eugenie celebrated Athena’s christening, their third cousin, Lady Amelia Windsor, went to the pub.

The granddaughter of the Duke of Kent attended a festive dinner with Chaumet at The Hart.

The venue, on the corner of Chiltern Street and Blandford Street, is named after the Hart family.

The pub is said to celebrate “British farmers, producers and seasonal ingredients” from their Market Garden at Bruern Farms.

Private dining at The Hart is priced at £88 per person, which includes three starters, two mains and two desserts served at the centre of the table for guests to share.

Across shores in the US, Beatrice’s husband, Mr Mapelli Mozzi, has been warmly described as “lovely” after meeting with art and design professionals, according to an Instagram post that highlighted his striking work on luxury residences.

Representatives from Galerie Provenance – a midcentury design and antique specialist with showrooms in Los Angeles and Bridgehampton – met Mr Mapelli Mozzi and associate Marco Peruzzi from Banda Property just before the Christmas holidays.

The team praised their friendliness and aesthetic sensibilities in a social media post, in addition to admiring their personally-designed Woodland House.

They wrote: “I had the pleasure to meet @edomapellimozzi and @peruz of @banda.property in Los Angeles before the holidays, and they were as lovely in person as their gorgeous residences.

“This is the beautiful Woodland House.”

The brief but glowing description offered a rare public compliment focused on Mr Mapelli Mozzi’s personality rather than his high-profile royal connections.
