SnagRes checks Maria Isabel on OpenTable continuously. The release time is confirmed against Maria Isabel's own booking listing. Last checked 7 September 2026.
Maria Isabel takes a bit of patience. About 3% of the next 30 days was bookable for two when we last checked, so the trick is being there when something frees up. We check OpenTable continuously and let you know the moment it does.
Prime time is the hardest slice here: just 8% of the 691 open slots we have seen fall between 7:00 and 8:30 PM. Widening to an earlier or later seating is the single biggest thing you can do.
52% of what opens up here is 9:00 PM or later, so a late dinner will get you in faster than waiting for a different date.
The times we see open run from 5:00 PM to 9:00 PM, and the single slot that opens most often is 9:00 PM.
We have never once seen a Sunday or a Monday come open, which usually means Maria Isabel is closed then rather than simply full.
OpenTable windows run long, often 60 to 90 days, so the far edge of the calendar rarely matters. What moves is the near term, as people cancel and rebook.

Frequently asked questions about booking Maria Isabel
How hard is it to get a reservation at Maria Isabel?
At the last check, 3% of the 30-day booking window had a table open for two at Maria Isabel, which puts it among the harder rooms we track. About 8% of open slots land between 7:00 and 8:30 PM. SnagRes checks OpenTable continuously and emails you when that changes.
What time can you actually get a table at Maria Isabel?
The open times recorded at Maria Isabel run from 5:00 PM to 9:00 PM, and 9:00 PM is the slot that comes open most often. These are the times left available, not the restaurant's full service hours.
What is the best party size to book Maria Isabel?
Two and four book about equally at Maria Isabel in our data, 3% of the window open for two against 3% for four, so party size is not the lever here. Shifting the night or the seating time moves availability more.
Is Maria Isabel open on Sunday?
We have never recorded an open table at Maria Isabel on a Sunday or a Monday, which normally indicates a closing day rather than a full book.
What time do Maria Isabel reservations open?
Maria Isabel releases reservations 30 days ahead, at 7:00 AM. OpenTable windows run long, often 60 to 90 days, so the far edge of the calendar rarely matters. What moves is the near term, as people cancel and rebook. SnagRes also watches continuously, so cancellations arriving off-schedule are caught the same as scheduled drops.
How far ahead does Maria Isabel release tables?
Maria Isabel releases reservations 30 days ahead, at 7:00 AM. A new date appears at the far edge of that window each cycle, and cancellations can surface at any point in between.
Which booking platform does Maria Isabel use?
Maria Isabel takes reservations on OpenTable. OpenTable windows run long, often 60 to 90 days, so the far edge of the calendar rarely matters. What moves is the near term, as people cancel and rebook. SnagRes watches OpenTable for Maria Isabel continuously and emails you the moment a table opens.
Why is it so hard to get into Maria Isabel?
Only 3% of Maria Isabel's 30-day booking window was bookable for two at the last check, and just 8% of the slots that open fall between 7:00 and 8:30 PM. Most tables here surface as cancellations rather than fresh releases, which is why watching continuously beats refreshing at a fixed hour.
Can you walk in at Maria Isabel?
SnagRes tracks reservations rather than walk-ins, so we cannot see a live bar count. With only 3% of the booking window open at the last check, Maria Isabel is not a dependable walk-in, and a reservation is the surer route. Some rooms keep a few bar or counter seats for walk-ins, so it is worth calling Maria Isabel to confirm; otherwise star it and let an alert catch a cancellation.
Is using a reservation alert legal?
Yes. SnagRes only notifies you when a table opens; the booking itself is an ordinary reservation you make yourself on OpenTable, under your own name. It does not resell tables, run bots to hold them, or automate the booking, so it does not cross the lines a resale or auto-booking service does.
Does SnagRes book Maria Isabel for me?
No. SnagRes tells you the moment a table opens at Maria Isabel and links you straight to OpenTable with the date prefilled, then you complete the reservation yourself. It never logs into your account and never books on your behalf, which is what keeps your account in good standing.
