One of a series of watercolours of London's Waterloo Station, during WWII, by Helen McKie (d 1957), showing a soldier being served by a waitres at a Milk Bar. Prior to the 1930s, milk was primarily perceived as a drink for children. Milk bars, an American idea which had flourished during the prohibition years, sold a variety of milk cocktails marketed at adults. The first English milk bar opened in Fleet Street, London, in 1935, and their numbers increased with the stationing of American troops in Britain during WWII.
