Cuisine of California The au jus sandwich is also known as roast beef au jus, and is better known in America as the french dip sandwich. It traces its origins to downtown Los Angeles in either 1908 or 1918, when a local restaurant owner was making a sandwich for a police officer and accidentally dropped it into a pan of beef broth. The officer liked the sandwich so much that he brought some friends in the next day for the new invention. From that point on, the Au Jus sandwich went on to become internationally known. Two Los Angeles restaurants claim to have created the sandwich: Philippe The Original and Cole's Pacific Electric (P.E.) Buffet. Both have been in operation since 1908.
