As you step into KOYN discover MIDORI, inspired by the landscape of Japanese zen gardens and the dazzling pink moss growing on the fertile volcanic soils of Mount Fuji.

Sushi Bar

Showcasing a mountainscape referencing Mount Fuji, our hand-carved boutique marble sushi bar is decorated with a bespoke and glamorous illuminated eglomise art piece.

Dine at our residential Sushi Bar, the centrepiece of MIDORI, where handcrafted sushi rolls, nigiri and sashimi are freshly prepared in front of guests under the guidance of KOYN’s resident Sushi master.


Descending downstairs, arrive at our immersive subterranean dining room, MAGMA, which mirrors the dark volcanic insides and fiery depths of Mount Fuji.

Set against the backdrop of handmade terracotta Japanese roof tiles and crisp black oak ceilings, MAGMA is home to our binchotan Robata grill and private dining room.


Take a seat at our marble dining counter overlooking the flames of our open kitchen and discover the smoky flavours of our Robata highlights.
