Bourdon House

Mayfair is an affluent area in the West End of London towards the eastern edge of Hyde Park, in the City of Westminster, between Oxford Street, Regent Street, Piccadilly and Park Lane. It is one of the most expensive districts in the world.The area was originally part of the manor of Eia and remained largely rural until the early 18th century. It became well known for the annual "May Fair" that took place from 1686 to 1764 in what is now Shepherd Market. Over the years, the fair grew increasingly downmarket and unpleasant, and it became a public nuisance. The Grosvenor family (who became Dukes of Westminster) acquired the land through marriage and began to develop it under the direction of Thomas Barlow. The work included Hanover Square, Berkeley Square and Grosvenor Square, which were surrounded by high-quality houses, and St George's Hanover Square Church. By the end of the 18th century, most of Mayfair was built on with upper-class housing; unlike some nearby areas of London, it has never lost its affluent status. The decline of the British aristocracy in the early 20th century led to the area becoming more commercial, with many houses converted into offices for corporate headquarters and various embassies. Mayfair retains a substantial quantity of high-end residential property, upmarket shops and restaurants, and luxury hotels along Piccadilly and Park Lane. Its prestigious status has been commemorated by being the most expensive property square on the London Monopoly board.

It was founded by entrepreneur Mark Birley and named after Lady Annabel Vane-Tempest-Stewart, then his wife. Annabel's was founded in 1963 after Birley's friend John Aspinall decided that they needed somewhere to party after an evening's gambling. As a result, Birley turned the basement of Aspinall's casino, the Clermont Club, into a nightclub, and named it after his then-wife, Annabel, who went on to marry Birley's friend, Sir James Goldsmith. In 2018, Annabel's moved to a new location, a Grade I listed Georgian mansion house at 46 Berkeley Square. Set across 26,000 square feet and positioned just two doors down from where its original location first opened in 1963, Annabel's is an all-day and all-night private Members’ Club.

The Alexandra Club was a private members club for women in Edwardian London. It was based at 12 Grosvenor Street, at the east end of the street on the north side, in London's Mayfair district. The club was founded in 1884, and closed in 1939. The club had 600 members by 1888.Membership of the club was only available to women eligible to attend the Queen's Drawing Rooms. Amy Levy in her 1888 novel, The Romance of a Shop considered the merits of the Alexandra Club against other clubs for women and concluded that the phrase "who has been or who would probably be precluded from Her Majesty's Drawing Rooms" to be "full of the sound and fury of exclusiveness and signifying not so much after all". Smoking was forbidden at the club, and members were not permitted to entertain men. Accommodation was available.The entrance fee was 5 guineas, with the annual subscription fee 4 guineas for members from the country, and 5 guineas for those in town. The popularity of the club led to disputes between members over the best tables those in which according to the historian Anne de Courcy, the "lunchers could be viewed in all their glory from the street". The Prince of Wales, visiting his wife, Princess Alexandra, was once denied entrance by the footman of the club. The prince's satisfaction over this caused him amusement and led him to say that the club was entitled to bear his wife's name as a result.

Gordon Ramsay at Claridge's was a restaurant owned by Gordon Ramsay and located with Claridge's hotel in Mayfair, London. Blackstone Group had enquired about Ramsay's availability to open a restaurant after he was awarded three Michelin Stars at Restaurant Gordon Ramsay. It marked the first of a number of restaurants that Ramsay would open at hotels owned by Blackstone. It opened in 2001, and by the fourth year was making a profit of £2 million a year. Mark Sargeant was the chef de cuisine of the restaurant until 2008, during which time the restaurant was awarded a Michelin star. The initial contract was for ten years, and after it was extended for three further short periods, Ramsay withdrew from negotiations with the new owners of the hotel and closed the restaurant at the end of the lease on 30 June 2013. It was positively reviewed by critics upon its launch, although work was required by staff to reduce the numbers of complaints it received from diners. Whilst some restaurant guides such as Zagat gave the restaurant positive reviews, Harden's did not. Both Sargeant and his successor Steve Allen won awards for cheffing when they worked at the restaurant.
