“Vienna Beef hotdogs are the best there is. Period. End of discussion.” So asserts Chris Caudill, the behind-the-counter owner of Roy’s Chicago Dogs at the Yard, where his wife Sara and mother-in-law Ginny Schropp are co-owners. Outside, the place doesn’t look like much, and its Corona Road location in the Petaluma Livestock Auction Yard may seem odd. But it’s historically accurate. The yard has been the site of one diner or another since the 1940s.
