Experience Japanese Cuisine at KOYN in Mayfair, London

Chōwa in Japanese means “the search for balance and harmony.” KOYN, Mayfair’s latest addition, nails this idea, offering a pitch-perfect expression of duality and compatibility.

Setting the Scene

An enthusiastic greeting of “Irasshaimase!” rings out as guests weave their way through the zen garden-inspired space housing the boutique sushi bar MIDORI. This airy space features hints of soft blue and pale pink—a sharp contrast to the robata kitchen downstairs, fittingly named MAGMA as an ode to Mount Fuji. Though both spaces share the same menu, the interiors in MAGMA are inspired by volcanic lava, with terracotta-lined walls and fiery orange hues that create an intimate atmosphere, complemented by a DJ to enhance the experience.

Your Dining Experience

After extensive recipe testing, Executive Chef Rhys Cattermoul and his team have curated a compact yet thoughtful selection of classic plates and refreshing twists that lean into the duality that characterizes the restaurant. It’s only right to explore offerings from both the sushi bar and the robata grill.

Food Highlights

• The signature dry-aged sea bass and sweet shrimp with oscietra caviar in yuzu dashi soy offer a delicate starter.
• Chūtoro (semi-fatty tuna), best paired with sudachi soy, kizami wasabi, and yuzu pearls, helps cut the richness.
• Charred scallops and classic black miso cod exude umami with a touch of sweetness.
• Showstoppers include applewood smoked Chilean sea bass topped with shiso salsa verde and the remarkable agedashi tofu.

Drinks Menu

KOYN features a classic cocktail and robust sake menu curated by the resident sommelier; however, it’s the extensive collection of Japanese whiskies that truly impresses. Whiskies sourced from distilleries across Japan, including areas as high as 2,625 feet in the Nagano Alps to the coast of the Chita peninsula, are meticulously detailed on the menu, catering to spirit enthusiasts.

Non-Alcoholic Options

For those abstaining from alcohol, try the Akoya, a blend of Everleaf with shisho, coconut, and lychee for a light, refreshing experience. Alternatively, the spiced sour mocktail featuring Everleaf, vanilla agave, egg white foam, and a sprinkle of dried chili flakes provides a creamy kick—perfect before dinner in the resident bar upstairs.

Sustainable Practices

Despite many ingredients sourced directly from Japan, KOYN also implements locally sourced items, which consequently reduce the carbon footprint of the menu. Moreover, plans are in place to recycle shattered plates into Kintsugi tableware, honoring the Japanese art of repairing broken pottery with gold.

Accessibility

A glass lift is available in the two-story space, ensuring accessibility for those with mobility issues.

Conclusion

For an exceptional fine dining experience showcasing Japanese cuisine in London, KOYN is truly unparalleled. With its unique atmosphere, carefully crafted menu, and commitment to sustainability, it’s a destination worth visiting.
