The restaurants were carpeted, had table service, tablecloths, flowers, china and cutlery, and made the trappings of upmarket dining affordable to the working classes for the first time. They were located in London, Clacton, Brighton, Ramsgate, Margate and other seaside resorts in southern England. Menus were expanded in the early 20th century to include meat dishes and other variations as their popularity grew to a total of thirty restaurants. Sam Isaacs' trademark was the phrase "This is the Plaice", combined with a picture of the punned-upon fish in question. A glimpse of the old Brighton restaurant at No.1 Marine Parade can be seen in the background of Norman Wisdom's 1955 film "One Good Turn" just as Pitkin runs onto the seafront; this is now the site of a Harry Ramsden's fish and chips restaurant. A blue plaque at Oldham's Tommyfield Market marks the first chips fried in England in 1860, and the origin of the fish and chip shop and fast food industries.
