Big Boy named franchisees
The Big Boy name, concept, menu, and mascot were originally licensed to a wide number of regional franchise holders. Because many of the early franchisees were already in the restaurant business when joining Big Boy, "Big Boy" was added to the franchisee name just as the Big Boy hamburger was added to the franchisee's menu. In this sense, it is confusing when referring to a chain, as each named franchisee was itself a chain and Big Boy could be considered a chain of chains.
People tend to know Big Boy not simply as Big Boy, but as the franchise from where they lived such as Bob's Big Boy in California, Shoney's Big Boy in the south, Frisch's Big Boy in much of Ohio, Marc's Big Boy in the Upper Midwest, Elias Brothers' Big Boy (or sometimes just Elias Brothers') in Michigan, among many others.
Each regional franchisee typically operated a central commissary, which prepared or processed foods and sauces to be shipped fresh to their restaurants. However, some items might be prepared at the restaurants daily, such as soups and breading of seafood and onion rings.
