Semma Cancellation Policy: Fees, Deposits, and No-Shows

As of September 2026, Semma does not publish a cancellation fee, a deposit amount, or a no-show charge anywhere a guest can read before booking. We checked the restaurant’s own site, and the only booking facts it states are that reservations go live 15 days in advance at 9am Eastern, that the book runs through an online reservation flow (the site’s reservation button currently opens a SevenRooms booking page), and that parties of seven or more are routed to private dining instead. There is no fee schedule, no policy page, and no printed deadline. What that means in practice is simple: whatever Semma asks of you, a card on file, a cancellation cutoff, a per-person penalty for a late change, is shown on the booking screen for your specific date and party size at the moment you confirm, and that screen is the only authoritative source. If you were hoping for a single dollar figure to plan around, the honest answer is that Semma has chosen not to advertise one. For the full picture of why this table is so contested in the first place, the main guide is how to get a reservation at Semma.

Deposits and prepayment: what the booking screen actually asks for

People search for Semma’s deposit in six or seven different phrasings, is it refundable, how much is it, what is the policy, and all of them run into the same wall: the restaurant does not put a number in public. That is not evasion, it is how most top New York rooms now operate. The platform holds your card as a promise rather than charging you up front, and the penalty terms attach to the individual reservation. A Tuesday two-top and a Saturday six-top at the same restaurant can carry different terms, and restaurants revise these settings without announcing it, which is exactly why a static policy page would go stale. So treat any figure you find on a forum or a year-old blog post as expired. The reliable procedure takes ten seconds: go through the booking flow to the confirmation screen, and read the fine print above the confirm button before you tap it. If it mentions a charge for cancelling inside a window, that window is your real deadline. If it only asks for a card with no stated fee, you are holding the table on good faith, and the cost of flaking is your standing rather than your money. The wider pattern across Resy, SevenRooms, and OpenTable venues is laid out in how restaurant cancellation policies actually work. One Semma-specific wrinkle worth knowing: the venue has appeared on Resy as well as through the SevenRooms flow its own site links to, and terms can differ by channel, so book through the restaurant’s own site link when you want the terms the house intends.

Is there a cancellation list?

No, not in the way callers usually imagine. There is no clipboard at the host stand where a name gets crossed off and yours gets penciled in, and emailing the restaurant to ask for one will get you a polite version of this same answer. What exists instead is mechanical: when someone cancels a Semma reservation, the slot goes straight back into the online book, visible to anyone looking at that date. On a book this contested the audience is enormous, Semma’s notify demand runs well over a thousand names deep on popular dates, so a returned table is less a waitlist and more a starting pistol. The useful part is that returns are not random. Cancellations cluster in a predictable wave: the 24 to 48 hours before service, when whatever penalty or courtesy deadline a booking carries comes due and people finally admit the dinner is not happening. A second, smaller trickle lands same-day, in the afternoon and the last hours before service, from the plans that fell apart too late to care about the deadline. So the day before your target date, and the morning of, are when a real seated table at Semma is most likely to exist for someone who did not win the original 9am release. The mechanics of that release itself are covered in when Semma reservations open, and the general theory of timed releases in how timed reservation drops work.

How to actually catch a cancelled table

Knowing the wave exists and catching a table inside it are different problems. A freed slot at Semma survives for seconds, because everyone watching the date sees it at once, and the people who win are the ones who happen to be looking at the right moment with a card already saved. Manually, your best imitation of that is narrow but real: check the date the evening before around the time penalty windows close, again mid-morning, and again mid-afternoon, with your account logged in and your party size preset so a found table is two taps from booked. Off-hours checks beat prime-time checks, since fewer rivals are looking at 11pm than at 6pm. This is also the one place software has an honest edge over a person, which is what SeatSwiper is for: it watches your exact date and party size around the clock and books the moment a cancellation surfaces, on your own account and in your own name, so the 1am return you would never have seen becomes your table. And if no table ever comes back, remember the escape hatch from the main guide: the bar is full service and held for walk-ins, so an early weeknight arrival beats any cancellation strategy for a party of one or two.

Changing or cancelling without burning the table

If your plans wobble, cancel early rather than late. A cancellation made days out costs you nothing under any plausible version of the terms, gives the restaurant time to resell the seat, and keeps your account clean. Moving the time or resizing the party is done through the same booking flow you reserved in, and at a room this full a change is really a cancel plus a fresh booking, so do not release your current slot until the new one is confirmed. Reservations are also expected to be used by the person who booked them; the name on the reservation should match somebody at the table, since sold and traded reservations are exactly what these systems are built to squeeze out. And whatever you do, do not simply not show up. A no-show at a restaurant with a thousand people wanting your chair is the one move that can plausibly follow you, platforms track repeat no-shows at the account level, and it wastes a seat someone on that date wanted badly.
