Past event: Dinings SW3's September residency at The Oarsman, Marlow, ran 17 to 20 and 24 to 27 September 2026, with lunch at £85 and dinner at £115.
Updated 29 September: this residency has finished. The Oarsman’s page still describes the September dates and has not announced another run.
The Chelsea Japanese restaurant Dinings SW3 returned to Marlow in September for two four-day residencies at The Oarsman, with twelve sittings across the two weekends and tickets sold in advance.
Executive chef Masaki Sugisaki and his team take over The Room Upstairs, the first-floor dining room at The Oarsman, 46 Spittal Street, on 17 to 20 September and again on 24 to 27 September. Both venues have published the dates and prices on their own sites. Marlow is about four miles south of High Wycombe.
Guests sit together at a single shared table and are served a multi-course omakase menu, which means the chef chooses the dishes rather than the diner. The Oarsman describes the cooking as rooted in Japanese technique with a subtle European influence. Dinings says many plates follow Sugisaki’s “gill-to-tail” approach to using a whole fish.
The sittings
Each weekend runs to the same pattern. Lunch is a 1pm arrival, dinner a 7pm arrival.
| Day | Sittings |
|---|---|
| Thursday 17 and 24 September | Dinner only |
| Friday 18 and 25 September | Lunch and dinner |
| Saturday 19 and 26 September | Lunch and dinner |
| Sunday 20 and 27 September | Lunch only |
What it costs
- Lunch: £85 per person. A slightly shorter menu than the dinner sitting.
- Dinner: £115 per person.
- Every sitting opens with a welcome cocktail, included in the ticket.
- A short a la carte drinks list is available alongside the pairings.
Check the pairing price before you book, because the two sites do not say the same thing. The Oarsman lists a flat “Wine & Sake Pairing, £60” and “Non-Alcoholic Pairing, £40”. The Dinings SW3 booking page prices them by sitting instead:
- Lunch: £40 with alcohol, £20 without.
- Dinner: £60 with alcohol, £30 without.
The Dinings page is the one that takes the payment, and its checkout lists all four pairing options separately, so that is the version to plan around. Both sets of figures are quoted here exactly as each site publishes them; confirm yours at the point of booking.
Booking and the small print
Tickets are sold through the Dinings SW3 site, sitting by sitting, at £85 for each lunch date and £115 for each dinner date. Three conditions are worth reading before you pay:
- Dietary requirements must be flagged when you book. Dinings’ terms say the event cannot accommodate them otherwise. Vegetarian menus are available with advance notice.
- Cancel inside 48 hours and you are charged the full ticket price.
- Extra drinks bought on the night are cash only, according to The Oarsman.
What is on the menu
The menu is set by the chef and led by what is in season, so it is not published in advance. The restaurant’s own announcement names a few of the plates guests can expect: koji-cured venison tartare, charred hand-dived scallops and a dedicated sushi course, alongside seasonal dishes in Sugisaki’s own style. Dinings says many of them follow the gill-to-tail principle of using the whole catch rather than a single prime cut.
Sugisaki said of the return:
“We are delighted to be returning to The Oarsman following such a special residency earlier this year. The Room Upstairs creates a wonderfully intimate setting, where guests can come together around one table and enjoy the menu as a shared experience. The Oarsman’s commitment to sustainability and carefully sourced produce also closely reflects the values behind the food we create at Dinings SW3.”
Who is coming
Dinings SW3 opened in 2017 and is approaching its tenth anniversary. Its restaurant is at Walton House, Lennox Gardens Mews, on Walton Street in Chelsea, and it describes itself as izakaya-inspired, elegant but informal, with a menu that changes weekly.
Sugisaki grew up in Saitama, north of Tokyo, where his family ran a kaiseki restaurant. He trained in Japan and London and was part of the opening team at Nobu Berkeley Street before opening his own restaurant.
The host has had a good year of its own. The Oarsman, a bistropub and wine bar on Spittal Street with head chef Scott Smith in the open kitchen, was awarded a Bib Gourmand by the Michelin Guide in 2026. It buys from local suppliers and regeneratively farmed producers, which is the common ground the two kitchens cite for working together.
This is not the first outing in Marlow. The Oarsman’s own page describes the September dates as a return “following a successful residency earlier this year”.
What it means for you
This is a fixed-price ticketed event, not a normal restaurant booking, so the usual walk-in and table-for-two logic does not apply. You are buying a seat at a shared table for a set menu at a set time, and the 48-hour cancellation rule means a late change of plan costs the full amount.
The practical decisions are the sitting and the pairing. Lunch at £85 is the shorter menu and the cheaper pairing; dinner at £115 is the full one. Adding the alcoholic pairing takes a dinner ticket to £175 a head on the Dinings pricing, before any extra drinks.
If you are coming from High Wycombe, note that The Oarsman is on Spittal Street rather than Marlow High Street, and that its own summer hours have the kitchen serving lunch from noon Thursday to Saturday. Booking enquiries for the residency go through Dinings; enquiries about hiring The Room Upstairs go to the pub on 01628 617755.
More things to do across the area are listed in things to do in High Wycombe, and the next big Marlow fixture in the diary is the Marlow Half Marathon on 1 November.
