How to Get a Reservation at I Cavallini in Williamsburg

I Cavallini is the Italian restaurant at 284 Grand Street in Williamsburg, and it introduces itself on its own site in one line: “Sister restaurant to Michelin starred and James Beard award winning The Four Horsemen.” Resy’s editorial blog covered the opening in July 2025 under the headline “The Four Horsemen Team Gallops Across Grand Street With I Cavallini,” and about a year later the room turned up on The Infatuation’s September 2026 list of the toughest reservations in New York. Some of that demand is pedigree. Anyone who has spent a month of mornings failing to book the sister restaurant already knows the name, and now there is a second Grand Street address to try. The useful thing about I Cavallini is that a real share of its seats never goes near the reservation app at all, and the route to those seats is unusually well documented. Here is how it works as of September 2026.

Resy is the only book, and the morning starts at 8

There is one way to reserve. The restaurant’s site says “all reservations via resy,” and its BOOK ON RESY button goes straight to the I Cavallini venue page on Resy. That is the whole online book. A phone call or a message to the restaurant’s Instagram is not a booking channel, and nobody at the door can add you to a calendar that lives somewhere else. The posted hours are 5pm to 10pm every day, dinner only, seven nights a week.

What the restaurant does not post is its booking window. The figure you will see quoted comes from The Infatuation’s September 16, 2026 guide to the toughest reservations in NYC, which says: “I Cavallini releases reservations two weeks in advance at 8am.” Treat that as well sourced but secondhand. Before you build a morning around it, open the Resy page a day or two ahead and look at the last date the calendar lets you select. If the furthest bookable night is fourteen days out, the window is what The Infatuation says, and you can count back from the dinner you want. If it reaches further or stops shorter, believe the calendar over any guide, this one included.

The hour needs its own warning. Plenty of hard New York Resy books open at 9am or 10am, and people who chase several restaurants carry that habit around with them. An 8am Eastern start is early by that standard, early enough that an alarm set on autopilot goes off after the good slots are gone. It is also not the sister restaurant’s clock: The Four Horsemen publishes a different hour and a longer window on its own site, so one alarm will not cover both. How opening times differ from platform to platform is laid out in the Resy vs SevenRooms vs OpenTable timing guide.

Why two weeks out turns into a sprint

A short window compresses everyone into the same few minutes. When a restaurant books a month or more ahead, the people who want a particular Saturday are spread across weeks of planning, and a good number of them book early and give the table back later. Two weeks out, the people looking at that Saturday have mostly made up their minds, and if the calendar moves forward a date at a time (check it the way described above) they are all looking at the same 8am on the same morning. Prime hours on Friday and Saturday go first. The practical version:

• Be logged in to Resy with a card saved before 8am, sitting on the venue page itself rather than a search results screen.
• Decide on two or three acceptable times the night before. Dithering between 7:30pm and 8pm costs more than taking either one.
• Aim at the edges of the evening. The 5pm opening slot or the latest time Resy shows is a different level of competition from the middle of a weekend night.
• Smaller parties have better odds. A table for two appears more often than a table for four, both when reservations open and when someone cancels.

The walk-in door is the whole bar and the counter

The most useful sentence anyone has published about this restaurant is, again, from The Infatuation’s September 2026 guide: “All of the bar and counter seats are saved for walk-ins.” Read that as a map of the room. A part of I Cavallini never appears on Resy at all, so no amount of speed at 8am puts you in those seats. The people sitting in them got there by standing on Grand Street in the late afternoon.

The same guide is precise about the timing: “line up outside no later than 4:30pm. When the place opens at 5pm, you should be seated right away.” Half an hour on the pavement against two weeks of alarms is a trade most people should take. Treat 4:30pm as a latest time, not a target; on a Friday or Saturday, turning up at 4:15pm is not paranoia. It is simplest to arrive together, since seating a group whose other half is still on the train is awkward anywhere. And because the restaurant opens at 5pm every day, the line is an option on any night of the week, not just the nights you failed to book. The broader question of which hard rooms keep a genuine door open is covered in do hard restaurants take walk-ins.

The first seating is the easiest table in the house

There is a second line in The Infatuation’s entry that is easy to skim past: “in our experience, you can also get a walk-in table during the first seating.” So the 4:30pm line is not only a line for bar stools. The likely reason is simple arithmetic. At 5pm the evening’s bookings have not all arrived, some tables will not be needed until later, and a party standing at the door when it opens is the most convenient way to use them. It also fits a pattern at nearly every hard restaurant: the earliest dinner hour is the one most bookers skip. If eating at 5pm suits you, the line is probably a better plan than the alarm. If you need an 8pm table for a birthday, it is not, and the Resy book is where you should be spending your effort.

Weeknights are the realistic target

Every route on this page gets easier between Sunday and Thursday. Fewer people are working the Resy calendar for a Tuesday, fewer are waiting outside at 4:30pm on a Monday, and the first-seating walk-in table is less contested on a quiet night. With the restaurant open every day, there is no dark night to plan around. If your date is flexible, pick the weeknight first and leave Friday and Saturday to a cancellation watch.

Cancellations on Resy: the day before and the day itself

When a guest cancels, Resy puts the table straight back on the calendar, visible to anyone looking at that moment. There is no queue and no announcement. At a room this wanted, the returns tend to cluster where plans firm up: the day before, as people confirm or abandon their week, and the day itself, when a party of four becomes three or somebody’s evening falls apart at 4pm. Those are the hours worth watching, and they are the hardest to watch by hand, because a returned two-top at a restaurant on The Infatuation’s toughest list is unlikely to sit there for long. Resy’s Notify feature is the built-in answer, and it helps at the margin, but the alert reaches a lot of people at once and the table goes to whoever confirms first; the reasons are in why Resy Notify rarely gets you the table.

The Four Horsemen connection

The shared team is why most people search for I Cavallini in the first place, and it changes the plan a little. The two restaurants run separate Resy books with separate windows, so there is no combined calendar, and a reservation at one gives you nothing at the other. What they do share is Grand Street and a crowd. The Four Horsemen keeps its own walk-in seats under its own rules, which are laid out in our Four Horsemen reservation guide. Commit to one line per evening; queueing at one and hoping to switch to the other is how you end up eating nowhere.

Putting a watch on the Resy book

Everything above comes down to being on the Resy page at the one moment a table exists: 8am on the morning your date comes into range, if The Infatuation’s window holds, or the unannounced minute someone gives back a Thursday. SeatSwiper watches Resy, SevenRooms and OpenTable, and because I Cavallini takes every reservation through Resy, that covers its whole online book. You give it your dates and party size once, it keeps watching, and it books the table the moment one opens or someone cancels, on your own Resy account and in your name. Nothing is resold or transferred; it is an ordinary reservation you walk in and use. The first booking is free, then it is a flat $5 only when it actually books the table, with no subscription. A cancellation watch on a sold-out date costs $1 to start, charged when the watch begins even if no table opens, not covered by the free first booking and not refunded, plus the same $5 if it wins you the table. The honest limits: it only works on those three platforms, it needs your Resy login to book as you, and it can lose a race for a single table. It also cannot reach the bar or the counter, because those seats never go online. For those, the 4:30pm line on Grand Street is still the best free door in this guide.
