Last updated . Source: SnagRes availability record, 168,311 checks of House of Prime Rib through 19 October 2026. How we measure. Open dataset.
Book months ahead on OpenTable, where the window runs about a year, or watch a near date and take the cancellation: we have recorded 427 of them, most at the last seating. At any moment the room is 0% open.
About a year, on OpenTable. That is the longest window of any room we track in San Francisco.
10:00 PM most often. 97% of timed openings were at 9 PM or later; prime time was 2%.
No. Both party sizes are 0% across the record.
No. SnagRes watches the calendar and alerts you by email or text the moment a table appears. You book it yourself, in your own account, at the restaurant's own price. We never hold, resell or charge per reservation.
Yes, and in an unusual way: the calendar is enormous and full. Across 168,311 availability checks, House of Prime Rib has shown a bookable table for two on 0% of the dates in its window and a table for four on 17%. Over the whole record, 8% of the dates we have watched opened at some point, one date in twenty.
Most rooms we track book two to four weeks out. House of Prime Rib takes reservations a year ahead, and San Francisco has booked it a year ahead. The dates you can see are not the problem; the seats on them are.
Open rate, party of two: 0%. Party of four: 17%.
Dates that opened at some point in our record: 8%.
House of Prime Rib books on OpenTable, and its window is about a year, so there is no daily drop of one fresh date the way there is at a Resy room with a 30-day window. Tables become available when someone gives one back, and we have recorded 427 of those moments, dates going from closed to open under our watch.
That is a high count for a room this closed, and it is the whole story of how people get in: a year's worth of bookings produces a steady trickle of cancellations, each of which lasts minutes.
Release events recorded: 427, nearly all of them cancellations.
Late, when they open at all. In the seats we have been able to time, 97% of openings fell at 9 PM or later and the slot that came back most often was 10:00 PM. Prime time, 7:00 to 8:30 PM, accounts for 2%. The sample of timed openings is small, which is itself the finding: this room does not give back many seats, and the ones it gives back are the last seating.
9 PM or later: 97%. Prime time: 2%.
Book far ahead, or catch a cancellation, and there is no third route. If your date is months away, look now: the year-long window means a date next spring may still have seats where a date next week has none. If your date is soon, watch it and take the cancellation, and take the late seating when it comes, because that is the one that comes.
Party size does not help here; two and four sit at the same 0%. Flexibility about the date does, more than at almost any room we track, because the window is so long.
Book on OpenTable. The calendar runs about a year ahead.
For a date months away, look now.
For a date soon, watch it. 427 recorded cancellations say the seat comes back for minutes.
Take 10:00 PM when it comes.
No, and that is deliberate. SnagRes watches House of Prime Rib on OpenTable around the clock and tells you the moment a table appears, by email or text. You book it yourself, in your own account, at the restaurant's own price. Nothing is reserved, held or resold on your behalf.
Because you cannot say any of the above about a directory. SnagRes tracks 284 restaurants across New York, San Francisco, Los Angeles and Chicago, with 61,530,416 logged availability checks between the rooms with a full record. Nothing watching tens of thousands of restaurants can tell you that one Nob Hill institution books a year out, is 0% open at any moment, and gives back its seats at 10:00 PM, because nothing is watching it closely enough to count.
