Caesar salad is said to have been invented by Caesar Cardini, an American chef who moved to Tijuana during Prohibition, although it is popularly thought to have come from Caesar's Palace in Las Vegas. It is a salad of romaine leaves, decorated with halved hard boiled eggs and coated with an emulsified dressing of anchovies, oil, egg and hot seasoning. We were intrigued to go to Caesar's Palace and to find multiple moving walkways which drew you inexorably into the casino. Whilst it was easy enough to find your way in, it was almost impossible to find your way out.
