Jun was born in the US to Japanese parents, but he specialises in fine French rather than Japanese cuisine. Having started at Le Gavroche at the age of 19, Jun spent the next ten years working with some of London's best chefs in seven top Michelin star restaurants. He worked and trained at Chez Nico, The Capital, The Square, Les Saveurs and Marco Pierre White's restaurant, Harvey's. He also worked under Marco Pierre White at both The Restaurant and The Oak Room.

Jun Tanaka is currently the executive chef at London's Pearl Restaurant - decorated with over a million hand-strung pearls.
