The story
A printed paper bag from the 1930s states that the business was established in 1909. A shop opened on Llanmaes Street in Roath, Cardiff in 1913. Developed by Mary Clark, a second shop opened on Cowbridge Road East in nearby Canton in the 1930s. During World War II the first shop was closed due to wartime meat rationing. Dennis Dutch, Mary Clark's grandson, opened the third pie shop and bakery on 10 May 1955 in Bromsgrove Street, Grangetown. In 2005, Dutch celebrated the shop's 50th anniversary.
The family have since sold Clark's Pies in Cardiff to another bakery ending their association with Clark's Pies
In the 1920s, (Harold, Harry) Percy Clark left his mother Mary to branch out on his own, establishing a shop in North Street, Bedminster, Bristol, where he built his own business. The shop passed to Percy's sons, John, Ken and Roger Clark, who have all since retired. Keith Prested now owns Clark's Pies Ltd along with his partner, Roger's daughter, Dawn Clark, who continues in the family tradition as a director of the business, which is still located at 259 North Street, Ashton Gate, Bristol where it has been making pies and pasties continuously since the 1930s.
