How to Get a Reservation at Sushi Tetsu (Seven Seats)

Sushi Tetsu is seven seats. Not seven tables: seven counter stools in a tiny room at 12 Jerusalem Passage in Clerkenwell, where Toru and Harumi Takahashi have run their two-person omakase since 2012. It is the purest supply problem in London dining, and it books in the purest way: the entire following week opens in a single batch every Monday at 12pm. No month-out calendar to strategise over, no rolling window, no bar to queue at. One weekly moment, then the waitlist. Here’s the honest guide, as of July 2026.

How Sushi Tetsu’s book works

Sushi Tetsu takes reservations through SevenRooms, on its own booking page (sevenrooms.com/reservations/sushitetsu) rather than inside a marketplace app. That matters more than it sounds: SevenRooms powers the venue’s own page, so there is no central feed surfacing availability and no stumbling into an open seat while scrolling an app you already have. You have to know to go there. If you know Resy’s synchronized morning scramble (mechanics in when Resy reservations open), this is that same race with two twists: the venue chose its own moment, and the prize pool is seven stools. The platform differences are worth understanding before Monday; the full comparison is in Resy vs SevenRooms vs OpenTable.

The mechanics themselves are unusually clean. Every Monday at 12pm, reservations for the week ahead open, all at once. That schedule has been consistently reported for years (The Nudge and The Infatuation both describe the Monday noon opening, and it holds as of July 2026), and it means the booking horizon is never more than about a week. You cannot book Sushi Tetsu for an anniversary in September. You can only decide, this Monday, whether you want to eat there in the next seven days.

Why Monday noon is unlike anything else in London

London’s hard tables each keep their own rhythm, as of July 2026: Gymkhana opens two months out at 6am, Trattoria Brutto puts tables up 14 days ahead at 9am, The Devonshire puts three weeks of tables up on Thursdays at 10:30am. All of those are windows onto a rolling calendar. Sushi Tetsu is the only major London book that is a single weekly event: everything it will serve next week, opened together and contested together.

Do the arithmetic and you see why the minute matters. Seven seats, and, per third-party listings (Yelp’s, not anything the restaurant states itself), lunch Tuesday to Friday, dinner Tuesday to Saturday, closed Sunday and Monday. Treat those hours as approximate, but even generously, a full week at Sushi Tetsu is somewhere between several dozen and a low three-digit number of covers. That is the entire weekly inventory of one of the most loved sushi counters in Britain, and all of it goes on sale in the same sixty seconds. There is a neat irony in the schedule, too: if the listed hours are right, the counter is dark on Mondays, so the biggest moment of Sushi Tetsu’s week happens while the restaurant itself is closed.

The waitlist is not the consolation prize

At most hard restaurants the waitlist is where hope goes to nap. Here it is the main lane. The Infatuation’s advice is blunt: when nothing is available, and a few minutes past noon nothing usually is, add yourself to the waiting list. The math is what makes it work. When a party of two cancels at a seven-seat counter, nearly a third of the room just reopened. Cancellations that would be a rounding error at a hundred-cover restaurant are seismic here, and they surface one at a time, at unpredictable hours, to whoever is paying attention. Most people who actually eat at Sushi Tetsu seem to get in this way rather than by winning the Monday race outright, which is why treating the waitlist as an afterthought is the biggest mistake you can make with this book.

Cost, hours, and what to check before you book

• The omakase was reported at around £187 a person by The Infatuation. Treat that as a snapshot, not a promise: tasting-menu prices move, and the current figure is whatever the booking page shows.
• Lunch is a real lane. Per the third-party listings above, lunch runs Tuesday to Friday alongside five dinner services, which roughly doubles the number of weekly seatings you can aim at compared with dinner-only thinking.
• Read the terms before noon, not during it. London’s top end runs an aggressive deposit culture (£50 a head at Carbone London, fully non-refundable at Kitchen Table). Sushi Tetsu’s own terms are whatever its SevenRooms checkout shows, so look before the race starts.
• Don’t build a walk-in plan. No walk-in policy is publicly stated either way, but a seven-seat counter that sells out its week on Mondays has no meaningful walk-in capacity to plan around.
• Ignore the closure rumours. Small restaurants attract them. Sushi Tetsu is open and taking bookings as of July 2026, and nothing in current reporting suggests a relocation or hiatus.

Watching seven seats without living on the page

Sushi Tetsu asks for exactly two behaviours: be on the page at the right minute on Monday, and watch for cancellations at every other hour of the week. SeatSwiper does both. It watches your dates and party size on Resy, SevenRooms, or OpenTable around the clock and books the instant a table appears, whether that is the Monday noon opening or a late-night cancellation. It books on your own account, in your name. Set it once and walk away: the first booking is free, then a flat $5 only when it actually books you the table.
