FORMAT CHANGED: a la carte since Nov 2025, no longer the nine-course kaiseki. Daisuke Hayashi, trained at three-star Kikunoi in Kyoto. Ten seats at one counter, in a hinoki room built in Kyoto and reassembled here. Bincho charcoal and straw smoke

Jeff's note

Roketsu Restaurant

The room was built in Kyoto, shipped to London and reassembled here, hinoki walls and sliding screens intact (Time Out).

Why go

Daisuke Hayashi trained at Kikunoi in Kyoto, which holds three Michelin stars, and opened this in 2022 (Time Out). Ten seats, and the chef's table is the only table.

The cooking is built on fire and on conversation. Bincho charcoal and straw smoke are named by the kitchen as its core technique, sushi is made in front of you at the counter, and kappo, in the venue's own words, "means dining through dialogue: speaking with the chef, sharing your preferences, and shaping your own menu" (Roketsu). What arrives is "guided by the day's harvest."

Leonie Cooper gave it four stars in January 2025, when it ran a nine-course kaiseki menu, and described dishes delivered as stories told quietly: radish sliced thin across a soup to look like ice on a lake, red beans for new-year prosperity, an eyeball made from egg wrapped in conger eel, a hot pot served in a ceramic castle tower (Time Out).

Then it changed. Time Out's own update line, dated November 2025, reads: "Roketsu is now an a la carte restaurant." Nobody has reviewed it since, and the venue's page still calls itself a tasting menu.

Order this / avoid

  • Order: whatever came off the bincho, since the charcoal and straw are the technique the kitchen leads with. Sushi at the counter. Beyond that, tell the chef what you like, because that is what kappo means here.
  • Avoid: booking on the assumption of a nine-course kaiseki. That format ended in November 2025. Turning up without a reservation, with ten seats in the room.

What locals & experts say

  • Leonie Cooper, Time Out, January 2025, four stars out of five, on the room: "At Roketsu the chef's table is the only table, and if the bleached, hinoki wood walls and sliding screens make you feel as if you've been transported to Japan, that makes sense - the room was built in Kyoto before being shipped and reassembled in London." ref
  • The same review, on the register of the place: "Despite all the formalities... there is something deeply chill about Roketsu... everything here is so measured and elegantly formal, that all you have to do is simply turn up." Her pull quote: "If only all meals were this relaxing." ref
  • The kitchen, on its own method: "Blazing binchō charcoal and the delicate aroma of straw smoke, a time-honoured Japanese technique, add depth and character." ref
  • No chef has named it, checked in the industry-vote file on 1 August 2026, and no review of the current format exists.

Good to know

  • Where: 12 New Quebec Street W1H 7RP, off Portman Square.
  • The format: a la carte since November 2025. It was a nine-course kaiseki tasting menu before that.
  • The room: ten seats at one counter, built in Kyoto and reassembled in London.
  • Booking: essential.
  • Price: $$$$. The tasting menu was described as not cheap; the a la carte prices were not established, so check before you commit.
  • Hygiene: FSA rating 5, inspected 31 August 2023, Westminster, components 5 / 0 / 5. That is the last inspection on file and it is nearly three years old. FHRSID 1413636. ref

Jeff's take (his words)

  • Note: none. His raw saved-places export carries an empty Note against this row. The master line "Daisuke Hayashi's kaiseki with a Kyoto-built counter" is curation text; the chef and the Kyoto-built room check out, and the word kaiseki is now out of date, which is the correction this entry makes.

Verdict (Chef Jeff ladder)

should-visit — Worth building an evening around, and check what you are booking before you do. Daisuke Hayashi opened Roketsu in 2022 after training at Kikunoi in Kyoto, which holds three Michelin stars, and the room he built is the first thing to know about it: hinoki walls and sliding screens, constructed in Kyoto, shipped over and reassembled in Marylebone. There are ten seats and the chef's table is the only table. The cooking runs on bincho charcoal and straw smoke, with sushi made in front of you, and the kitchen describes kappo as dining through dialogue, which means telling the chef what you want and shaping the menu with him. Leonie Cooper gave it four stars for Time Out in January 2025, when it was still a nine-course kaiseki menu, and caught the register exactly: for all the formality, the effect is deeply relaxing, and all you have to do is turn up. Here is the part every other page gets wrong. Time Out's own update line says that in November 2025 Roketsu became an a la carte restaurant. Nobody has reviewed it since, and its own site still calls itself a tasting menu, so go knowing that what you eat is now partly your choice.

Order

  • Anything off the bincho charcoal, since the grill and the straw smoke are what the kitchen is built on
  • Sushi made in front of you at the chef's table, which is the only table there is
  • Whatever the day's harvest gave them, because the menu is built on it rather than written in advance
  • The a la carte, which is new. This ran as a nine-course kaiseki tasting menu until November 2025

Good to know

  • Booking: essential
  • Timing: dinner, bookings-essential
  • Best for: dinner, date, big-night, solo
  • Avoid: Arriving expecting the old format. It became an a la carte restaurant in November 2025; Turning up without a booking. There are ten seats; A rushed dinner. The room is built for a slow one and the service is deliberately measured

    Roketsu (venue site, read 1 August 2026)

    FIRST-PARTY, AND THE CURRENT FORMAT. Self-description: 'At our core lies the craftsmanship of Japanese cuisine. Not to embellish tradition, but to let cuisine evolve, alive in the present moment. Guided by the day's harvest, each dish unfolds as part of a seasonal tasting experience inspired by the spirit of kappo.' THREE HEADINGS, WHICH ARE THE THREE THINGS THIS KITCHEN SELLS: 'Bincho Charcoal & Straw Smoke', 'Sushi at the Chef's Table' and 'Kappo-Style Dining'. On the fire: 'Blazing bincho charcoal and the delicate aroma of straw smoke, a time-honoured Japanese technique, add depth and character, an experience of fire and flavour for you to enjoy.' On the counter: 'Sushi takes shape at the Chef's Table, each piece crafted with artistry, precision, and elegance.' ON THE FORMAT, WHICH IS THE POINT: 'Kappo-style means dining through dialogue: speaking with the chef, sharing your preferences, and shaping your own menu.' The site's own title is 'Seasonal Japanese Tasting Menu in London | Roketsu Marylebone'. FETCH NOTE: 813 chars, a thin one-page site, which is above the 400-char failure threshold and so was used as returned

    Time Out London (Leonie Cooper, 16 January 2025), 4 out of 5, with a November 2025 update

    BYLINED, SCORED, AND CARRYING ITS OWN FORMAT CORRECTION AT THE TOP: '**November 2025: Roketsu is now an a la carte restaurant.**' The review beneath it describes the kaiseki format that preceded that change. THE CHEF AND THE PEDIGREE: 'Opened in 2022 by chef patron Daisuke Hayashi, who trained at Kyoto's triple-Michelin starred Kikunoi, Roketsu specialises in high-end kaiseki experience; a not-cheap tasting menu of which there are about as many courses (nine!) as there are seats in the restaurant (10!).' THE ROOM, AND THE FACT THAT MAKES IT: 'At Roketsu the chef's table is the only table, and if the bleached, hinoki wood walls and sliding screens make you feel as if you've been transported to Japan, that makes sense - the room was built in Kyoto before being shipped and reassembled in London.' THE COOKING: 'Our nine course menu of spectacularly seasonal dishes is delivered in the form of stories, quietly but clearly told. There's a layer of thinly cut radish across a bowl of soup made to look like ice on a lake, there are red beans to signify prosperity for the new year, and an all-seeing eyeball crafted from an egg wrapped in a sliver of conger eel. A hot-pot dish takes things even further, served in a ceramic castle tower.' ON THE REGISTER: 'Despite all the formalities... there is something deeply chill about Roketsu... everything here is so measured and elegantly formal, that all you have to do is simply turn up.' Her pull quote: 'If only all meals were this relaxing'
