In just a few short years, Oswalds has established itself as a favourite among the royals and the aristocracy.
The evening before the Coronation, on May 5, Mike and Zara Tindall joined Princess Beatrice, Princess Eugenie, Princess Anne and her husband Vice Admiral Sir Timothy Laurence at the club.
Turning the evening into a royal affair, and a celebration of what was to come the following day, they were also joined by the Duke and Duchess of Edinburgh, their two teenage children, Prince Andrew and Beatrice’s husband, Edoardo Mapelli Mozzi.
Just last week, the Duchess of Edinburgh was pictured leaving the club after dining there with friends.
Princess Eugenie has also celebrated her birthday at the club in the past, and Prince William having celebrated the festive period.
Speaking of the royal guests, Daily Mail’s diary editor Richard Eden said: “Prince William and Catherine were among the first to visit.
“They were followed by everyone from Prince Andrew and his daughters to Prince and Princess Michael of Kent and their children.”
The club is owned by British entrepreneur Robin Birley. Opening the club in 2017, he named it after his grandfather Sir Oswald, who was a royal portraitist.
Robin also owns and runs 5 Hertford Street nearby – the location where Prince Harry and Meghan Markle reportedly had their first date in 2016.
Eden added that the “key thing that Oswald’s owner, Robin Birley, guarantees is discretion”.
He continued: “Frustratingly, for a social diarist like me, Oswald’s members are ultra-discreet and so we rarely hear what goes on behind its doors.”
