 As legend has it, someone there, maybe Cardini, maybe his brother, desperately threw together a few provisions on hand. Olive oil, lettuce, parmesan, egg, the salad at Caesar's Restaurant was a hit. It still is. We have a little Worcestershire, a very small amount of lemon juice and Tabasco. Caesar's salads today, like at the New Orleans restaurant Boucherie, often include anchovies.
