Our contemporary izakaya features modern Japanese cuisine that is authentic with a traditional influence.

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

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