One of London's oldest gay pubs, the King William IV in Hampstead has been a gay hangout since the 1930s. There's a good mixture of clientele, many of whom pop in for a few drinks after a walk on nearby Hampstead Heath. You'll often find a long queue outside for the adjacent crepe stall (also highly recommended!).
