Born Marilyn Friedman in Cleveland, she moved to Los Angeles with hopes of working as a movie costume designer. When she met young actor Harry Lewis, the pair began dreaming of opening a restaurant on their very first date.
Aiming to appeal to actors who wanted something simple and comforting after working all day, they opened the first Hamburger Hamlet at Sunset Blvd. and Hilldale before they were married, drawing customers including Ronald Reagan, Sammy Davis Jr., Elizabeth Taylor, Bette Davis, Lucille Ball, Frank Sinatra, and Tony Curtis.
Hamburger Hamlet opened more locations, including in Beverly Hills on Beverly Drive, and the restaurant became known as the first place to serve gourmet, customizable hamburgers with unusual toppings. Other memorable dishes included “Those Potatoes” and the Lobster Bisque.
After helping conceive the look of the restaurant and the sophisticated slant of the menu, Marilyn Lewis launched the Cardinali fashion line in the 1960s. The expensive, luxurious clothes were worn by socialites and stars, most famously by Marlo Thomas on the show “That Girl.”
The family sold the chain in 1987 and went on to open Kate Mantilini on Wilshire Blvd., which also became a favorite casual industry eatery until its closure in 2014.
Harry Lewis died in 2013. Marilyn Lewis is survived by sons Adam and David and five grandchildren.
