 An Italian immigrant by the name of Caesar Cardini had a packed house at his restaurant. It was prohibition. Most of his customers were Californians who'd crossed the border to drink, and they were hungry. Cardini needed to feed them something, so he threw together what he had in the kitchen. Romaine lettuce, an anchovy, some garlic, Dijon mustard, lime juice, croutons, Parmesan cheese. A legend was born. This month, Tijuana will honor Cardini with a three-day Caesar salad festival and his own statue. Sherry Preston, ABC News.
