Avenida Revolución was the first road in Tijuana to be paved, near the beginning of the twentieth century. Originally called Avenida Olvera, it was from its earliest days a popular destination for American tourists who crossed the border from California. The avenue's most remarkable development was during the Prohibition Era of 1920-33, when it was visited by American tourists seeking legal alcohol. The Caesar salad was invented on Avenida Revolución during this period by Caesar Cardini, the Italian-American proprietor of the Hotel Caesar and its restaurant Caesar's.
