[6] Birley blocked off the staircase due to his disapproval of Arab gamblers coming down into Annabel's from the Clermont Club in various states of "dress and disorder which jarred with the tone of the nighclub" as recalled by Jonathan Aitken.

[7] Lady Annabel herself said that she was not fond of having the club named after her when it first opened but subsequently looks back " ... on [Birley's] decision with pride and consider it the most tremendous compliment he could ever have paid me.

I had visions of oxygen masks and people being trampled to death" but " ... by the early hours of the morning the crowd miraculously began to melt away, and the rest of the night was magical".

[4] Annabel also accidentally insulted the American ambassador to the United Kingdom, David Bruce, and the actor Peter O'Toole by telling them there was no room for them.

[4] Lady Annabel recalled that the guests on opening night " ... sounded like a roll call for the pillars of society".

[10] Plum Sykes described how "Birley's collection of horse and dog paintings and prints covered the walls top to toe; flickering candle lamps lit the tables while guests ate dinner seated on banquettes upholstered in red velvet; the cramped dance floor, almost an afterthought, was hidden at the back of the club and boasted only a couple of disco lights ...

[4] The supporting pillars of the basement were covered with an antique brass which caused atmospheric reflections contributing to the intimate ambience of the club.

[9] Birley placed sandbags outside the club as a precaution against terrorist attacks following the IRA's bombing of Scott's in nearby Mount Street in 1975.

[8] A set of linocuts of scenes from Annabel's by the cartoonist Nicholas Garland was privately published by Birley in 1985, with a foreword by Lucian Freud.

[4] The social commentator Peter York said that someone once described Annabel's as being where the "middle-aged meets the Middle East" and that it had represented the "high point of aspiration" in the 1980s but that it was unsustaniable if it only catered to Sloane Rangers.

[15] Barry Humphries wrote and performed a special song about Annabel's on both nights in character as Dame Edna Everage.

[15] Queen Elizabeth II visited the club in 2003 for a dinner to celebrate the 70th birthday of one of her Ladies of the Bedchamber, Virginia Ogilvy, Countess of Airlie.

[18] In 2004 India Jane became pregnant and Robin paid former London police officers who claimed to be private detectives more than £400,000 from the accounts of Annabel's in exchange for false information about her then partner, and the father of her child, Robert Macdonald.

[8] Many notable entertainers subsequently performed live at Annabel's including Ray Charles, Bryan Ferry, Ella Fitzgerald, Lady Gaga, Diana Ross, The Supremes, and Tina Turner.

[8] Mabel was particularly keen that all women would wash their hands after visiting the toilet, and would stand next to the basin with a towel and fill it with warm water.

[17][4] Prince Andrew, Duke of York was also once barred from entry to Annabel's after wearing jeans with an open necked shirt.

The rule was quickly reimposed however as Birley described in an article for The Spectator that he had " ... overlooked the simple truth that the British have no tradition of casual clothes.

We seem to have a uniform for everything: weddings, births, funerals, racing, shooting, hunting, fishing, dancing, dining in the City, attending concerts ... Consequently on those occasions when we are invited to use our initiative, it is invariably a disaster".

[28] Blasberg is particularly excised about couples who wear matching clothes as it is "annoying and gimmicky" but intends his list to "encourage individuality and fabulous party dressing, and step back from being binding or overly prescriptive".

[9] Upon his death in 2007 Mark Birley left the majority of his estate valued at £120 million and his possessions to India Jane to be kept in trust for her son, Eben, in his will.

[11][31] Annabel's was the subject of the 2014 documentary film A String of Naked Lightbulbs, directed by Greg Fay and produced by Ridley Scott.

In an article for Vogue about Annabel's reopening Plum Sykes wrote that "For a tiny elite, this is the London aesthetic of now—out-and-out gilt-trimmed maximalism" and that "a Birley inspired joie de vivre has exploded into the decor".

[11] In his book More More More, Lawrence Llewellyn Bowen wrote that people were "gobsmacked" at the new Annabel's: "What was once a Sloane safe space with politically dodgy, days-of-the Raj print chintz was now decked out like a tart's boudoir.… It was as if a museum of bad taste and interior design cliches had been gloriously and unrepentantly gussied up into a blancmange of high-kicking snogtastic naughtiness"; nevertheless he concluded that "it was, and remains, an enormous success".

[42][43] In the entrance hall of the club hangs the 1937 painting Girl with a Red Beret and Pompom by Pablo Picasso of his lover Marie-Thérèse Walter.

[39] The Garden Room at Annabel's is a restaurant with a gilded ceiling with roses painted by Gary Myatt with walls of mirrored panels.

[11] With over 575,000 likes, The Powder Room was the second most popular toilet on Instagram in 2019, behind only the futuristic eggs of Mayfair restaurant Sketch.

[37] Annabel Sampson wrote in Tatler that if the Powder Room was a cake " ... it would be a splendid, seven-tiered red velvet gateau with rippled icing like classical drapery".

[37] The other prominent bathroom, the Loos on the Mews were opened in 2019 and are decorated in a jungle and rainforest theme with four million pieces of mosaic of trees and exotic birds.

[45] The men's bathroom features a crocodile shaped washbasin made from a piece of green onyx weighing 500 kg.

Brudnizki said of the Loos on the Mews that the "jungle and animal motifs add to the playful spirit of the place ... offering members a similar sense of escapism to the rest of the Club".
