There are additional stores at The Royal Exchange, St Pancras railway station and Heathrow Airport in Greater London, at K11 Musea in Hong Kong, as well as various stockists worldwide.

[3] Founded as a grocery store, Fortnum's reputation was built on supplying high quality food, and it saw rapid growth throughout the Victorian era.

[5][6] The store began to stock speciality items, namely ready-to-eat luxury meals such as poultry or game served in aspic jelly.

[8] Charles Drury Edward Fortnum (1820–1899), of the family, was a distinguished art collector and a Trustee of the British Museum, to which he donated his collection of Islamic ceramics.

Every hour, 4-foot-high (1.2 m) models of William Fortnum and Hugh Mason emerge and bow to each other, with chimes and 18th-century style music playing in the background.

The chimes were incorporated into Jonathan Dove's orchestral adaptation of Zeb Soanes' children's book Gaspard's Foxtrot, which depicts the clock and its figures as illustrated by James Mayhew.

[20][23] In November 2010, animal rights group PETA UK began a campaign against Fortnum & Mason's sale of foie gras, citing the cruelty in the production process.

Celebrities supporting the campaign included Geezer Butler, Sir Roger Moore,[24] Owain Yeoman,[25] Tamara Ecclestone,[26] Bill Oddie,[27] Twiggy[28] and Morrissey.

[30] As a result, the grocer changed its corporate social responsibility document to state that only UK suppliers are required to adhere to its welfare standards.

In the 2022 film Living (a re-make of the Akira Kurosawa classic Ikiru), the stricken protagonist takes his young companion to lunch at the Fortnum lunchroom, to her astonishment.

In Alan Bennett's play The Madness of George III (also made into a 1994 film), set in the late 1780s, a footman named Fortnum leaves in a huff to start a "provision merchant's in Piccadilly."

This is an anachronistic reference to the founding of the store, as William Fortnum's position as a footman in the royal household was many decades earlier, in the reign of Queen Anne.
