Sushi Tetsu

Seven seats. Three or four hours. Upwards of £200 a head. Book it anyway.

Sushi Tetsu is a 7-seat omakase counter in a Clerkenwell alley, and it has held a dedicated following for nearly 15 years. Opinionated About Dining ranked it #164 among the Leading Restaurants in Europe in 2025 (up from #182 in 2024), which tells you the room is not coasting on nostalgia. If you are deciding whether to commit the time, the money, and the effort to secure a seat: yes, commit. This is among the most focused sushi experiences available in London, and the format — quiet counter, no distractions, a meal that takes the time it takes — is the point.

What to expect at the counter

The setting at 12 Jerusalem Passage is deliberately spare. Seven seats, no background noise to speak of, and a pace set entirely by Toru Takahashi and his wife Harumi, who runs the front of house with the same attentiveness her husband brings to the fish. The atmosphere is closer to a private dining room than a restaurant: hushed, unhurried, and oriented entirely around the counter. Leave your phone away, this is one of those rooms where taking it out would feel conspicuous, and the venue makes that expectation clear. For a special occasion or a date where the quality of conversation matters as much as the food, the format works precisely because external noise is absent.

Planning across visits: what changes and what doesn't

The omakase format means the menu moves with the season and with what Takahashi considers worth serving that week. A first visit gives you the baseline: the counter dynamic, the pacing, the interaction with both chef and host. A second visit, ideally in a different season, is where the value compounds, the menu shifts enough that returning diners are not eating the same meal. If you are planning two visits in a year, aim for one in late autumn (when certain cuts of fish are at their leading in Japanese culinary tradition) and one in spring or early summer. The experience at the counter is consistent in quality; what varies is the selection, which is reason enough to return. A third visit, for those who have settled into the format, can be treated as an annual fixture rather than a special-occasion booking.

Booking: frustrating but manageable

This is where Sushi Tetsu asks the most of you. There is no website and no active online presence. A booking link exists on SevenRooms but offers limited information. The most reliable approach is to email info@sushitetsu.co.uk directly, this is confirmed as the working contact for reservations. Given the 7-seat capacity, availability is genuinely constrained, but the venue is not impossible to book if you plan ahead. The booking difficulty rating here is manageable rather than prohibitive, provided you make contact well in advance and are flexible on dates. Walk-ins are not a realistic option at this scale.

Practical details

Budget upwards of £200 per head once drinks are included. The meal runs three to four hours, so treat it as the entire evening rather than one part of it. The address is 12 Jerusalem Passage, London EC1V 4JP, a short walk from Barbican or Farringdon stations. There is no dress code on record, but the room's intimacy and price point suggest smart casual at minimum. For context, this is a comparable spend to CORE by Clare Smyth and The Ledbury, but the format is radically different: no tablecloths, no brigade service, no wine list theatrics, just a counter and a chef who has been doing this for fifteen years in the same room.
