The River Tyburn was a stream (bourn) in London, its main successor sewers emulate its main courses but it resembled the Colne in its county of Middlesex in that it had many distributaries (inland mouths). It ran from South Hampstead, through Marylebone and Soho (St Anne's, Westminster) then ran through St James's parish/district and Green Park to meet the tidal Thames at four sites, grouped into pairs. These pairs were near Whitehall Stairs (east of Downing Street) and by Thorney Street, between Millbank Tower and Thames House. Its much smaller cousin the Tyburn Brook was a tributary of the Westbourne, in turn the next Thames tributary (west, on the north bank). A charter of AD 959 appears to mention the river, which it refers to as Merfleot, which probably translates as Boundary Stream, a suggestion reinforced by context, with the river forming the western boundary of the estate described.

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.
