Our dining destination and contemporary izakaya features Japanese cuisine that is authentic with a modern influence.

Dishes from our boutique Sushi Bar, binchontan Robata Grill and kitchen under the guidance of Executive Chef Rhys Cattermoul are designed to be shared.

In addition to classic favourites, our menu showcases KOYN’s signature dishes and specials for the season alongside a bespoke collection of Japanese whiskies, hand-picked sakes and wines thoughtfully curated at the KOYN Bar.
