Lyons' Corner Houses were large restaurants owned by J. Lyons & Co., operating in London between 1909 and 1977.   Reasonably priced, with live orchestra music and sometimes open 24 hours a day, they provided a range of services (including food-halls, hairdressers and telephones) and were enormously popular until tastes began to change in the 1960s.
