6-year-old food and beverages critic from Connecticut, Leo Kelly has become a sensation for his brutally honest reviews of the popular mocktail Shirley Temple. Calling himself the Shirley Temple King, the class 1 boy posts his reviews about the non-alcoholic beverage on Instagram and mind you, the little fellow is not easily impressed! His grades range from one to ten and he shares that he's never gone beyond 9 and a half! A Shirley Temple is traditionally made with ginger ale and grenadine syrup.
