Burger King

One of Burger King's worldwide favourite specialties is a hamburger called a "Whopper".

When Burger King decided to expand their operations into Australia, they found that their business name was already trademarked by a man running a small takeaway food shop. Resultingly, the first Australian franchise of the Burger King Coporation, established in Perth, was aptly titled Hungry Jack's, echoing the name and sentiment of the franchisee, Jack Cowin. Hungry Jack's sells the usual range of burgers, but also an Australian specialty, the Aussie Burger. This burger is based on the traditional Australian fish and chip shop[?] favourite, including fried egg, bacon, onion and beetroot with the traditional meat, lettuce and tomato.
