Set an alert on the specific restaurants and dates you want, then stay flexible on party size and time. At the hardest New York tables the release is gone instantly, so a last-minute seat is a cancellation, and an alert that rechecks every 15 minutes catches it before you ever could by refreshing.
The same way as in New York, by watching for cancellations rather than fresh releases. In San Francisco the extra step is coverage, because restaurants split across Resy, OpenTable, Tock and SevenRooms, so make sure your alert watches every platform the restaurant uses, not just one app.
You cannot predict when a cancellation lands, so the only reliable method is continuous watching. A tracker rechecks the restaurant on a fixed interval and alerts you the moment a seat returns to the pool, which is the short window when a canceled table is bookable before anyone else grabs it.
No, cancellations surface at no fixed hour, which is why sitting on a page waiting for one does not work. They do cluster in the last 48 hours before a date as plans fall through, so the day before and the day of are the richest times to be watching for one.
Often, yes. Tables for two are the most contested inventory at almost every hard restaurant, while four-tops sometimes have more give at the last minute. Trying an adjacent party size, or an earlier or later seating, frequently surfaces a table that looked impossible for two at prime time.
No, and that is deliberate. SnagRes watches availability and emails you the instant a table opens, then links you straight to the restaurant's own booking page so you complete the reservation yourself. It alerts, it does not snipe, which keeps it clean under every platform's rules.
At the hardest restaurants, a last-minute table almost never comes from the normal release. Of the roughly 140 restaurants SnagRes tracks across New York and San Francisco, 42 show a bookable slot on zero percent of days over their normal booking window. For those, the calendar is effectively empty from the moment it opens, so waiting for a fresh drop is not a plan.
That means a same-day or next-day seat almost always comes from a cancellation. Someone books weeks ahead, their plans change, and the table falls back into the pool for whoever happens to be watching. Cancellations are the real supply of last-minute tables, and learning to catch them is the entire game.
Cancellations do not arrive at a fixed clock time. There is no magic hour when tables reappear, and no restaurant announces the moment a guest bails. Openings surface unpredictably, and a single opening can last only a few minutes before someone else claims it.
That is exactly why refreshing by hand loses. You cannot sit on a booking page all day, and the one time you step away is usually the time a table blinks into view. A continuous watcher solves this: SnagRes rechecks each tracked restaurant every 15 minutes and emails you the moment a slot appears, so you find out without staring at a screen.
Cancellations concentrate in the final 48 hours before a date, as plans fall through and no-shows get released back. The day before and the day of are the richest windows, especially the afternoon ahead of a dinner service. This is the opposite of the release game, where you fight a crowd at the drop; here you are simply waiting for other people to give tables up.
The time inside the service matters too. Prime slots between 7 and 8 PM are the most contested, so they clear last and hardest. The seats that open up first are the ones fewer people compete for, so widen your window toward the edges of service whenever you can.
The reliable method is to stop hunting and let a watcher do the waiting, then stack a few flexibility levers on top. In rough order of how much each one moves your odds, here is what genuinely works.
Set an availability alert on the exact restaurants and dates you want, so you are notified the instant a table appears.
Be flexible on party size, because tables for two are the hardest to find and four-tops sometimes have more give at the last minute.
Be flexible on time, since very early seatings around 5:30 and very late ones after 9:30 open up far more often than prime 7 to 8 PM.
Watch the day of and the day before, when no-shows and cancellations peak and seats flow back into the pool.
Check every platform the restaurant might use, not just Resy, because SevenRooms and Tock tables are easy to miss.
The mechanism is identical in both cities: the hardest tables are gone at release, and the way in is a cancellation you were positioned to catch. What differs is which platform a given restaurant uses. New York leans heavily on Resy, while San Francisco spreads across Resy, OpenTable, Tock and SevenRooms, so checking a single app quietly hides half the city.
SnagRes covers all four platforms in both cities, so one alert watches a restaurant wherever it actually takes bookings. That is the practical difference between hoping you happened to open the right app at the right minute and being told the moment a seat frees up.
A last-minute table at a hard NYC or SF restaurant almost always means catching a cancellation. Set an instant alert instead of refreshing all day.
