Semma releases tables 15 days ahead at 9 AM Eastern on SevenRooms. At our last check a table for two showed on 0% of the next 30 dates, though 27% of dates opened at some point, so after the drop the way in is a cancellation, caught by a text the moment it appears.
No. Semma books on SevenRooms, not Resy, and there is no second platform holding its tables. SevenRooms is where the 9:00 AM release happens and where every cancellation reappears. Across 350,114 checks of that calendar we have recorded an open table 1,137 times.
The stated rule is 15 days ahead at 9 AM Eastern, on SevenRooms. Our logs add a wrinkle: across 337 observed release events on 58 days, the hour we most often saw a new date appear was late in the evening. We publish the 9:00 AM rule, and we suggest a late-evening look as well.
You book Semma on SevenRooms, either at the 9:00 AM release 15 days before your date or by catching a cancellation afterward. Because a two-top was open on 0% of the dates in the current 30-day window, most diners who get in are catching a freed seat rather than winning the morning release.
Tuesday, then Wednesday. Tuesday dates have produced 393 of the openings we recorded and Wednesday 252, against 93 on Friday and 80 on Saturday. No Sunday check has ever found a table.
Rarely. About 7% of the 3,177 open slots we have sampled fell between 7:00 and 8:30 PM. Late and early are likelier, with 49% of open slots at 9:00 PM or later, 44% before 6 PM, and 5:00 PM the most frequent.
Semma is a Michelin-starred South Indian restaurant in the West Village, and by our numbers it is among the hardest Indian tables in the city to book. A two-top was open on 0% of dates in the current window, against 7% at ADDA and 23% at Dhamaka, all three of which release at 9:00 AM Eastern on SevenRooms.
At no fixed hour. They surface as plans change and parties shrink, and each freed seat is bookable only until the next person sees it. Because they are unpredictable and short-lived, an alert that fires the instant a table appears is the only reliable way to catch one without living on the booking page.

Semma releases reservations 15 days ahead at 9 AM Eastern, on SevenRooms. That is the rule to set an alarm by. Semma books on SevenRooms only, so there is no second platform holding back a table.
Our own logs complicate that picture, and we would rather show you the complication than hide it. Across 337 release events we observed on 58 separate days, the hour we most often recorded a new Semma date appearing was late in the evening, not 9:00 AM. We are not publishing that as the release time, because the restaurant's stated rule outranks our measurement, and a modal hour can be an artifact of when new inventory becomes visible to a checker rather than when a restaurant intends to open it.
What we will say is that a late-evening look has repeatedly found something, and it costs you nothing. The 9:00 AM alarm stays. Add a glance the night before and you are covering both the stated rule and the pattern we actually observe.
We can put numbers on any of this because we have run 350,114 availability checks against Semma's calendar, part of 61,530,416 checks across the 284 restaurants we follow. Watching a short list closely is what lets us tell you where the restaurant's rule and our observations disagree, instead of repeating one sentence about a room we never look at.
Semma is one of the hardest tables in New York by our reading. A two-top was open on 0% of the dates in the current 30-day window, and a four-top on 0%. Across 350,114 checks of its calendar we have recorded an open table 1,137 times in total, which is the scale of scarcity a percentage alone does not convey.
A near-zero reading does not mean Semma never seats anyone. Over the whole record 27% of dates opened at some point. It means a table almost never stays open long enough for an ordinary person to find it and take it. The 9:00 AM release is claimed in moments, and the 15-day window keeps everyone who wants the same Friday pressed into the same instant.
A two-top was open on 0% of the next 30 dates, and a four-top on 0%.
27% of dates opened at some point over the whole record.
In 350,114 checks of Semma's calendar we have recorded an open table 1,137 times.
The rule is 15 days ahead at 9 AM Eastern, on SevenRooms.
We have never seen a table open on a Sunday.
The start of the week, clearly and consistently. Tuesday leads with 393 recorded openings, followed by Wednesday with 252, Thursday with 152 and Monday with 167. Then the week falls off: Friday produced 93 and Saturday 80. Sunday has never shown us an open table at all.
That is the most actionable fact on this page. Anyone who searches for a Friday, finds nothing and concludes that Semma is impossible has measured one of the hardest nights of its week and called it the restaurant.
Treat a night we have never seen open as a night not to plan around rather than as a closure. We report what we have observed, which is that no Sunday check has ever found a table, and the useful consequence is the same either way.
Tuesday: 393 recorded openings. Wednesday: 252.
No Sunday check has ever found an open table at Semma.
Late or early, rarely in between. Of the 3,177 open slots we have sampled at Semma, 49% were 9:00 PM or later and 44% were before 6:00 PM. The single most frequently open slot is 5:00 PM, the earliest is 5:00 PM and the latest is 9:30 PM.
Prime time is thin but not empty. About 7% of its open slots fell between 7:00 and 8:30 PM. When a Semma table does appear at that hour, it is almost always a cancellation, and cancellations mirror what people booked in the first place, which is heavily prime time.
That is also why an alert beats a calendar habit here: the prime-time table exists, it simply does not wait.
All three release at 9:00 AM Eastern on SevenRooms and differ everywhere else. Semma releases 15 days ahead at 9 AM, ADDA 15 days ahead at 9 AM and Dhamaka 7 days ahead at 9 AM, which makes Dhamaka a much shorter runway to plan around.
The availability gap between them is wide. At our last reading Dhamaka showed a two-top on 23% of dates, ADDA on 7% and Semma on 0%. If what you want is an outstanding Indian table in New York this month rather than this specific dining room, that ranking is the useful thing to know.
Semma is also the one to set an alert on rather than to hunt by hand, because its openings are rare and short-lived. Dhamaka rewards someone willing to check a calendar; Semma does not reward that behavior at all.
Semma, West Village: 0% for a two-top and 0% for a four-top, with 7% of open slots at prime time.
Dhamaka, Essex Market: 23% for a two-top and 23% for a four-top, with 24% of open slots at prime time.
ADDA, East Village: 7% for a two-top and 17% for a four-top, with 10% of open slots at prime time.
Two paths work, and you should use both. The first is the 9:00 AM release 15 days out, with SevenRooms already loaded, party size chosen and a Tuesday or Wednesday in mind rather than a Friday. The second is a cancellation after the release is gone, which is where most Semma tables that reach ordinary diners actually come from.
Cancellations arrive on no schedule. They surface as plans change and parties shrink, and each freed seat belongs to whoever sees it first. A table released in the middle of a Tuesday afternoon is invisible unless something is watching Semma continuously, and nobody can refresh a booking page all day while holding down a job.
SnagRes re-checks Semma on SevenRooms around the clock and texts or emails you the moment a table matching your request appears. We do not book it, hold it or resell it. The alert reaches you and you book it yourself, in your own name, on SevenRooms, which is the whole difference between an alert service and a reservation broker.
Set the alarm for 9:00 AM Eastern, 15 days before the date you want, with SevenRooms already open.
Ask for Tuesday or Wednesday, which produced 393 and 252 of the openings we have logged.
Expect 5:00 PM or a late seat, the times that open most.
Add a late-evening look as well, since that is when we most often observe new dates appearing, whatever the stated rule says.
Set an alert for cancellations, which is where nearly every catchable Semma table comes from.

Semma releases reservations 15 days ahead at 9 AM, and its calendar runs about 30 days deep in our checks. At the last check a table for two was bookable on 0% of the dates in that window, so the release itself is the one real chance, and the rest come back as cancellations.
Because the tables that exist are gone at the drop. Across 350,114 checks, Semma has shown a bookable table for two on 0% of dates, though 27% of dates opened at some point. We have recorded 337 release events there. 7% of the openings we have seen were between 7:00 and 8:30 PM. The seats you can actually get are the ones that come back when someone cancels, which is why an alert on the date beats refreshing.
Semma's calendar reaches 1 December on Monday, 16 November at 9 AM, and each later date follows the same rule: 15 days ahead at 9 AM. Hours are local to the restaurant.
