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.
At a random moment, yes. Over a week, much less so. Across 252,010 availability checks, Maria Isabel has shown a bookable table for two on 0% of the dates in its window and a table for four on 0%. But 16% of the dates we have watched opened at some point before they filled, and we have recorded 175 release events, one of the higher counts in San Francisco. The calendar moves; a person checking it by hand at a random hour sees the smaller number.
Open rate, party of two: 0%. Party of four: 0%.
Dates that opened at some point in our record: 16%.
Maria Isabel books on OpenTable, and a new date appears at 7:00 AM, 30 days ahead. Seven is the earliest release hour of any room we track in the city, which is a quiet advantage for anyone willing to be awake for it: the competition at 7:00 AM is a fraction of what a 10:00 AM release draws. The window rolls forward one day at a time.
Release time: 7:00 AM, one new date each morning, 30 days out.
Both ends of the evening. The slot we have seen open most often is 9:00 PM, 51% of recorded openings fell at 9 PM or later, and 20% came before 6 PM. The 7:00 to 8:30 PM window accounts for 15%. Openings run from 5:00 PM to 9:00 PM.
Before 6 PM: 20%. Prime time: 15%. 9 PM or later: 51%.
Set a 7 AM alarm for a specific date, or watch the week and take the cancellation. With 16% of dates opening at some point and 175 recorded openings, the second route seats more people. Come as two rather than four: a four-top shows on 0% of dates against 0%, and ask for the early or the late seating rather than the middle.
Book on OpenTable. New dates appear at 7:00 AM, 30 days out.
Watch a week rather than a date. 16% of dates open at some point.
Ask for 9:00 PM or before 6 PM.
No, and that is deliberate. SnagRes watches Maria Isabel 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 Presidio Heights room releases at 7 AM and gives back 16% of its dates, because nothing is watching it closely enough to count.

Maria Isabel releases reservations 30 days ahead at 7 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 252,010 checks, Maria Isabel has shown a bookable table for two on 0% of dates, though 16% of dates opened at some point.
