In it's 59 years as a Hollywood celebrity hangout, Chasen's had ample time to develop recipes for special clients. However, Shirly Temple was one of only two people who had a recipe from Chasen's named for her. The story behind the drink is that Shirley, at the height of her fame as a child star, came to the restaurant with her parents, who were having a before-dinner cocktail. Shirley wanted one of her own, so the bartender concocted this one for her. Non-alcholic cocktails have been named "Shirly Temples" ever since.
This drink is served in a highball glass with ice, and garnished to look like a cocktail; and served with a straw. Other sodas can be substituted, such as a lemon-lime soda. Information from the archives of the Los Angeles Library.
