La Crêperie
Crêperie de Hampstead is a relatively recent landmark, mainly known for its queues and great Crêpes. Founded in 1977 by a French chef, it has traded from the same spot ever since.
 
The King William IV occupies 77 Hampstead High Street, NW3, sharing the site directly alongside La Crêperie de Hampstead, which opened in 1980 in a hatch on the pavement adjacent to the pub.  The two have been physically and commercially intertwined, with the crêpe stall historically using storage and utilities from the pub’s garden area, which later became the focus of a long‑running “crepe war” dispute.
 
From the early 2010s onward the pub became famous less for its ale and more for its acrimonious row with La Crêperie, sparked when the new landlady, Elaine Loughran, objected to the crêpe stall’s use of the pub’s garden and utilities.  Lawyers were involved, public support was rallied via petitions, and the story became a local‑media cause célèbre, often dubbed “Hampstead’s crepe war,” before the dispute was resolved with the stall moving its fridge and prep facilities off‑site while remaining on the pavement outside the pub.
