Trivia: The Doctor comes to Nevada in search of "A bowl of chili. The sort you only ever got in an American diner before 1962." During the 1960s, Chasen's Restaurant in Hollywood made a chili that became highly sought-after by celebrities (Elizabeth Taylor had some flown to Rome when she was making "Cleopatra."). Diners started changing their chili recipes in attempts to duplicate Chasen's secret recipe. This is why The Doctor had to go back to the 1950s in search of a bowl of old-fashioned American chili.
