Johnny Rockets is an American restaurant franchise whose themed decor is based upon 1950s diner-style restaurants. Decor includes Coca-Cola advertising featuring nearly life-size cardboard illustrations of women in World War II armed services uniforms, individual jukebox stations, chrome accents and red vinyl seats. The staff at some locations are known to sing and dance every half-hour. Making a smiley face with ketchup on the paper plate when serving French fries is a Johnny Rockets trademark.
