Kaiseki in Marylebone: Where London's Japanese Fine Dining Sits in 2025

London's premium Japanese dining scene has developed in two broad directions over the past decade. One strand runs toward the theatrical — wagyu-heavy omakase counters in Mayfair that price against the city's most expensive European tables. The other holds closer to the restrained Kyoto tradition, where the point is not abundance but precision: seasonal ingredients, a counter format that invites conversation, and technique that refuses to announce itself. Roketsu, which opened on New Quebec Street in Marylebone roughly four years ago, belongs firmly in the second category. Chef-patron Daisuke Hayashi has built a kaiseki programme that sits in the upper tier of London's Japanese offer — rated among the highest-performing Japanese venues in EP Club's annual diners' poll and holding a Michelin Plate in 2025 , while keeping its reference point clearly in kappo-style Kyoto dining rather than in the louder West End competition.

For context on where this places Roketsu in the city's wider Japanese field: venues like Umu in Mayfair and Ginza St James's operate in the same price bracket but with different format emphases, while Humble Chicken and Chisou occupy lower price points and serve different aspects of the Japanese repertoire. Akira represents another node in the capital's high-end Japanese offer. Roketsu's specific niche , kaiseki menus with kappo interaction in a room that physically references Kyoto craft , gives it a distinct position within that competitive set.

The Counter Format and What It Demands

Kaiseki is often described in terms of its course count or its seasonal sensitivity, but the format's real discipline is simplicity under pressure. A bowl of dashi, a piece of grilled fish, a single vegetable preparation , each component must justify itself without the cover of complexity. This is the same logic that governs a bowl of carefully made soba or a clean, clear ramen broth: the fewer the elements, the more visible the skill (or its absence). Roketsu's counter format makes this dynamic explicit. Guests sit directly facing the kitchen, watching preparations unfold at close range, and the menu changes in response to what the day's market delivered. That interaction between availability and execution is the engine of the kaiseki tradition, and it is also the thing that separates a genuine counter experience from a tasting menu that merely takes place at a bar.

The counter itself is fashioned from 100-year-old hinoki wood , a detail that carries more than aesthetic weight. Hinoki (Japanese cypress) has been used in formal Japanese interiors, including bath houses and tea rooms, for centuries, valued for its grain, its faint cedar-adjacent scent, and its association with ceremonial spaces. In London, where most Japanese restaurant design operates on borrowed imagery, a counter of this material and provenance signals a different level of commitment to the source tradition. Comparable reference points in the kaiseki world exist in Tokyo at venues like Myojaku and Azabu Kadowaki, where material choices and spatial restraint carry the same communicative function as the food itself.

The Menu Structure: Kaiseki Courses and À La Carte

The kaiseki menus run to seven courses at £160 per person or nine courses at £190 per person , prices that position Roketsu squarely in London's top tier for Japanese dining, though not outside the range set by peers in the same neighbourhood and format category. The technique range across the menu is broad: raw preparations, tempura, charcoal-grilled items, and straw-smoked meats are all documented in the kitchen's output, with the common thread being what reviewers have described as deep, aromatic flavours drawn from traditional method rather than modern augmentation.

For guests who find the multi-course format either too structured or too expensive, the à la carte offers an entry point, with most main dishes priced at approximately £50. This is not a concession to the casual diner so much as an acknowledgement that kappo-style dining historically allowed individual ordering alongside the chef's progression , the kaiseki format grew from simpler kappo roots, and the coexistence of both options here reflects that lineage. For price-bracket comparison in London's wider fine dining field, tables like The Fat Duck in Bray, L'Enclume in Cartmel, and Moor Hall in Aughton operate in a comparable spend range within the UK's tasting-menu tier, as do London-based options including Gidleigh Park in Chagford, Hand and Flowers in Marlow, and Le Manoir aux Quat' Saisons in Great Milton. Roketsu's per-head spend is consistent with that cohort, though the format is categorically different.

Breaking: Closure and Renewal from July 2025

In July 2025, Roketsu announced a temporary closure from 1 July for renovation and what the restaurant described as a renewed concept. The existing ratings, menu pricing, and format details documented here reflect the restaurant as it operated before closure. What the renewed concept will entail is not yet known. For a venue that has built its identity on the specific disciplines of kaiseki and kappo format, any shift in concept will be worth watching closely. EP Club will update this listing when the restaurant reopens and its new direction becomes clear.

Marylebone as a Setting for This Kind of Dining

Marylebone's dining character differs from Mayfair's in ways that matter for a venue of this type. The neighbourhood accommodates a higher density of specialist, format-led restaurants , places where the point is the cooking tradition rather than the room or the celebrity association. New Quebec Street in particular sits on the western edge of Marylebone's main dining corridor, close enough to the Portman Square end of the district to feel removed from the more conspicuous West End traffic. For a kaiseki counter that depends on a certain quietness of atmosphere, this is a more coherent location than, say, Dover Street or St James's.
