Contemporary Izakaya & Japanese Dining Destination
Our restaurant, located on Mayfair’s prominent Grosvenor Street, is inspired by the nature-spirited roots and duality of Mount Fuji, honouring Japanese traditions and culinary craftsmanship.
Executive Chef Rhys Cattermoul showcases a broad spectrum of Japanese cuisine through delicate umami flavours and responsibly sourced ingredients.

Join us for the return of our inaugural Bar Residency series this winter! We play host to Barcelona’s legendary ‘Five-star dive bar’, Two Schmucks on the 30th of November, and pioneers of Milanese aperitivo, Camparino in Galleria, on the 13th of December.
Each bar will present exclusive cocktails exemplifying their approach to mixology.
