London fog. London fog may refer to the so-called pea soup fog in London in the late 19th and early 20th centuries. London Fog may refer to: London Fog (beverage), an Earl Grey tea-based drink. London Fog (cocktail), an alcoholic drink made with gin and Pernod. London Fog (company), a popular manufacturer of coats and other clothes. London Fog (nightclub), a 1960s nightclub on the Sunset Strip where The Doors first played as a house band.
In combination with climatic conditions this often caused a characteristic smog, and London became known for its typical London Fog, also known as Pea Soupers. London was sometimes referred to as The Smoke because of this. In 1952 this culminated in the disastrous Great Smog of 1952 which lasted for five days and killed over 4,000 people.
