When Do Gymkhana Reservations Open?

Gymkhana takes reservations on SevenRooms, through the JKS Restaurants booking page rather than a marketplace app, and the answer to the timing question is an early one: the booking guides that track London’s hard tables agree that a new date becomes bookable at 6:00am UK time, exactly sixty days ahead. One caveat worth stating plainly, because this site tries not to sell you false precision: that 6:00am figure comes from those guides agreeing with each other, not from a rule Gymkhana publishes on its own page. As of September 2026 it is the best-evidenced answer available, and the sane move is to confirm it against the venue’s own SevenRooms calendar in the week before your date comes into range, by watching when the newest day appears. The full playbook for actually winning the table lives in the main guide to getting a reservation at Gymkhana; this page is the short, timing-specific version.

What time do bookings open?

6:00am in the UK, on the reporting available, which makes Gymkhana one of London’s dawn races rather than a mid-morning one. That hour is not an accident. JKS opens the far edge of the calendar before the workday starts, which rewards the people organised enough to set an alarm and quietly filters out everyone who planned to look after breakfast. It also means the race is over early: for a two-Michelin-star room with this much demand, the consistent reporting is that Friday and Saturday dinner slots can be gone within the hour, and the prime seven-to-nine window goes much faster than that. If you check at 9am you are not late to the race, you missed it entirely. Different platforms structure this moment differently, and the general mechanics of a timed opening, and why some venues drop a whole month while others roll one day at a time, are covered in when restaurant reservations open.

How far in advance can you book

Sixty days. The window rolls, meaning one new date enters range each morning rather than a whole month appearing at once. So if you want a specific Saturday, count back sixty days from it and that morning at 6:00am is your single densest moment of supply for the entire cycle. There is no way to book further out than the window allows, no waitlist that jumps the queue, and no phone line that quietly holds inventory the internet cannot see. The sixty-day figure carries the same caveat as the hour: it is the consensus of the booking guides, not a number printed by the restaurant, so treat the pairing of six o’clock and sixty days as reliable enough to plan around and cheap to verify. Watch the SevenRooms calendar for two consecutive mornings and you will see both numbers confirmed or corrected in front of you.

What happens at the release minute

The new date flips live for everyone simultaneously. Every person in London, and a fair number of visitors planning trips, who wants that particular Saturday is pointed at the same instant, and the dining room only holds so many prime tables. The arithmetic is unkind: hundreds of intents, a handful of seats, and the whole thing decided in roughly the time it takes a checkout screen to load. Being logged into your SevenRooms details in advance, card saved, party size already chosen, matters more than any amount of refresh speed, because the losers of this race are mostly people typing payment details while the seats disappear. Even played perfectly, a manual attempt at a table this contested is a lottery ticket. Take the 6:15 or the 9:30 you can actually get, or a weeknight, and hold it while you keep working on the slot you wanted. A weekday lunch, meaningfully softer than dinner at the same two-star kitchen, is the other honest answer the release minute cannot take away from you.

Cancellations are the second wave

Missing the opening is not the end, because the opening is only the first of two times a table exists. Plans collapse constantly over a sixty-day runway, and every collapse puts a table straight back on the public SevenRooms book. Gymkhana lists no deposit on the dining room as of this writing, and that detail changes the shape of the second wave: with no fee deadline herding everyone into cancelling by a tidy cutoff, give-backs trickle in at random hours, the Tuesday afternoon someone’s trip falls through, the morning of, sometimes hours before service. How deposit rules shape this rhythm across restaurants is laid out in restaurant cancellation policies. The catch is that a returned Gymkhana table is visible to everyone at once and survives for seconds, so casually re-checking the page a few times a day almost never catches one. The people who win the second wave are the ones looking at the exact moment it breaks, which for a human is luck and for software is the job description.

Set the watch once and stop doing dawn maths

Both of Gymkhana’s winnable moments are attention problems. One happens at 6:00am on a morning you have to calculate, the other happens at an hour nobody can predict. SeatSwiper exists for exactly this shape of problem: tell it the Gymkhana date range and party size you want, and it watches the venue’s SevenRooms book around the clock, booking the instant a table appears, at the release or from a cancellation alike. It books on your own account, in your own name, nothing resold, and it charges a flat $5 only when it actually lands the table, with the first booking free. It can still lose a synchronised race for a single seat, but it never oversleeps a sixty-day alarm and never blinks at 2pm on a Tuesday. Where Gymkhana sits among the city’s other dawn races, and which of them reward the same setup, is mapped in the hardest restaurants to book in London.

The short version to act on: SevenRooms via the JKS booking page, 6:00am UK, sixty days out, per the booking guides as of September 2026, prime weekend slots gone within the hour, and an untimed trickle of cancellations as the second chance. Confirm the minute on the venue’s own calendar before you build an alarm around it, and if the alarm life does not appeal, let a watcher run it instead.
