Carlton Club

Arthur's was a London gentlemen's club, now dissolved, which was established in 1811 and was disbanded in 1940. Between 1827 and 1940 it was based at 69 St James's Street. It is now best remembered for having built the London clubhouse currently occupied by the Carlton Club. The club was first formed at a meeting at a bank at 16 St James's Street on 8 May 1811, with the resolution 'That a New Club be forthwith established, to consist of 300 Members.' The club is notable for being the first to be a members' club wholly owned by the members, as opposed to the proprietary clubs which previously existed, like White's, Boodle's, and Brooks's, and it accordingly served as the mould for most of the nineteenth century members'-owned clubs which followed.

On 26 June 1990, the Provisional IRA detonated a bomb at the Carlton Club, a club in London popular among MPs and supporters of the ruling Conservative Party. The bombing injured 20 people, one of whom, Lord Kaberry of Adel, died a year later. The ground floor collapsed to the basement and windows were shattered. The blast was felt up to half a mile away. In a statement, the IRA said: "Like Brighton in 1984, the IRA has brought the war directly to those who keep the British Army on the streets and in the fields of Ireland. While such occupation continues, and the Nationalist people face daily oppression, the policy makers and their military arm will not be safe." The attack was part of the IRA's escalating campaign that started in early 1990 and which had claimed two lives and 27 injuries since May that year. Tory MP for Fulham Matthew Carrington called the attack very "worrying" as it was a non-military target, suggesting a dangerous tactic from the IRA against members of the public.The bomb contained 15 lb (6.8 kg) of Semtex explosives. Prime Minister Margaret Thatcher arrived at the club shortly after the bombing and spoke with some of the victims.

It has received considerable critical acclaim over the years. It was originally in Kings Road Chelsea, but relocated to St James's, London in 2015.Chutney Mary pioneered in redefining the public face of Indian cuisines by showcasing the gourmet foods from 6 to 8 different regions of India at any one time. It had the rigorous philosophy that the foods of the different regions could best be cooked by the chefs from that region.It was an extremely ambitious undertaking and akin to having a pan European gourmet. Chutney Mary was probably the first Indian restaurant in the world to trace the regional provenance of each dish. Chutney Mary was also pioneered as an Indian restaurant in taking wines seriously, and led the way in the pairing of Indian food and wine.The regional provenance and the dishes on the Chutney Mary proved the trailblazer for the supermarket packaged foods – e.g. Waitrose which from the mid-1990s started prepared dishes with the regional provenance and with names from the Chutney Mary menu.
