KOYN

The Japanese restaurant Koyn is just the latest in the long-line of striking Mayfair restaurants for the father-daughter duo Samyukta Nair and Dinesh Nair, whose collection includes Jamavar, MiMi Mei Fair, Bombay Bustle, as well as the upcoming Socca alongside Claude Bosi. 

Where is KOYN?

Located on Grosvenor Street, W1K 4AQ, KOYN is set within a two-storey building that has previously housed the Canadian High Commission and American Embassy. Nearby restaurants include Lucky Cat by Gordon Ramsay, 34 Mayfair, ROKA, Sexy Fish and The Twenty Two, as well as other LSL Capital establishments such as the Michelin-starred Jamavar.

What can diners expect from KOYN?

As with all of the LSL Capital ventures, the design is truly stunning. Designed in conjunction with Fabled Studios, the interior design of the restaurant has been laid out to symbolise Mount Fuji. In particular, the enigmatic combination of complementary forces that balance the lush alpine environment above ground with the fires raging below. 

The boutique Verde Cipollino sushi bar is located within the striking Midori room, a calming green room inspired jointly by the zen gardens of Japan and the snow-capped peaks of Mount Fuji, whose fertile soil is home to the flourishing pink moss. 

The below ground magma room represents the perfect contrast to the calming zen of above ground. The roaring charcoal-fuelled robota grill is the centrepiece of this volcano-inspired space. Built from black slatted timber and rainforest marble, guests are seated close enough to feel the heat from the flames. 

Rhys Cattermoul, best known for his previous work as the head chef of the Berkeley Square Nobu leads the kitchen as Executive Chef. KOYN’s menu promises to adopt the Japanese ancient appreciation of balancing modernity with tradition, showcasing the very best of Japanese cuisine through the delicate umami flavours but utilising responsibly sourced local produce. 

The restaurant will offer its take on the modern izakaya, the Japanese equivalent of a tapas bar or gastropub. Izakaya’s are popular across Japan, as traditional places where friends meet to share a drink of beer, sake or whiskey alongside a variety of dishes. 

The KOYN philosophy places priority and value on subtle details, where art, design and tradition combine with culinary craftsmanship to deliver a truly unique and unforgettable dining experience.
