It is the first time ever that a West Australian restaurant has won the prestigious award.

Known for its innovative and flavourful degustation menus, Restaurant Amusé, run by young couple Hadleigh and Carolynne Troy, can now safely lay claim to being the best in the business, beating rockstar rivals Tetsuya's in Sydney, Jacques Reymond in Prahran and Darley's Restaurant in Katoomba to win best fine dining in the country, and best restaurant overall.
