How to Get a Reservation at Zitz Sum (Coral Gables, Miami)

Zitz Sum is chef Pablo Zitzmann’s modern dim sum restaurant tucked into the lobby of an office building on Alhambra Circle in Coral Gables, a few minutes from Miracle Mile. What began as a pandemic dumpling pop-up became one of South Florida’s most decorated small rooms, a Michelin Bib Gourmand every year since 2022 and a James Beard Best New Restaurant semifinalist. The dining room is tiny and dinner only, five nights a week, so a menu that rewrites itself weekly runs headlong into a room that seats a fraction of the people who want in. That mismatch, not any velvet rope, is why a Zitz Sum table is genuinely hard to land.

How Zitz Sum reservations actually work

Zitz Sum takes reservations through OpenTable, not Resy, so if you have been refreshing a Resy page you are on the wrong platform entirely. Search the restaurant on OpenTable, set your party size, and open the calendar. The kitchen serves dinner Tuesday through Saturday, roughly 6pm to 9:30pm on weeknights and a bit later on Friday and Saturday, and it is closed Sunday and Monday, so those two dark nights will simply never appear. Reservations are held on a card and top out at six guests, with larger parties handled by calling the restaurant directly.

Seats tend to be released on a rolling window that moves forward a day at a time rather than in one big monthly batch, so the useful move is to know the exact date you want and be looking the moment it first enters that window. Our explainer on when restaurant reservations open covers how to time that, and how to tell whether a room drips out seats daily or opens a block at once.

Why the table is so hard to get

Three things compound here. First, the room is small, a single narrow dining room with a handful of tables, so even a sold-out night is a low cover count. Second, the food travels far beyond Coral Gables in reputation, the kind of Michelin and James Beard attention that pulls in out-of-towners and hometown regulars alike. Third, Zitzmann edits the menu constantly, swapping the bing, the bao fillings, the crudo and the multi-course tasting from week to week, which quietly turns a one-time dinner into a place people rebook to keep up.

Demand that renews itself against a fixed, tiny number of seats is the hardest kind to beat, which is why Zitz Sum sits comfortably among Miami’s hardest restaurants to book. If you are planning a wider Coral Gables or Coconut Grove night, Los Felix nearby is another small, chef-driven room that rewards the same tactics.

Off-peak angles that actually open seats

You do not have to fight for a Friday 8pm two-top. Between the seats most people skip and Zitz Sum’s own walk-in space, there is usually a way in:

• Try the bar or the courtyard lounge as a walk-in. Zitz Sum keeps space for walk-ins at its bar and the lounge tables out in the courtyard, and the restaurant points to 5pm or 9pm as the best windows to land one without a booking.

• Book the early or late edges. A 6pm Tuesday or Wednesday seating turns over far more often than prime weekend time, and you still get the full kitchen and the same weekly tasting.
• Ask for one or two seats, not a big party. A single open two-top appears constantly where a larger table almost never will, and since reservations cap at six anyway, solo or duo diners fit this counter-scale room best.
• Time it around the weekly menu change. Zitzmann rewrites the bing, the bao fillings and the tasting from week to week, which keeps regulars rebooking, so fresh cancellations churn constantly as those plans shift and a date just after a menu swap can loosen up.
• Check same-day and next-day. Late cancellations at a room this size reappear on OpenTable within a day of service, so a last-minute look often beats planning three weeks out.

When cancelled tables come back

Most returned seats at Zitz Sum are cancellations, not brand-new inventory. OpenTable restaurants typically ask guests to cancel a set number of hours ahead, and a freed table pops straight back onto the listing the instant someone bows out. That means prime slots quietly reappear a day or two before service, and again in the final hours as plans change, often at odd times like 6:15pm or 9pm that a casual searcher never catches.

It is worth understanding a venue’s cancellation policy so you know roughly when that window opens up. The catch is obvious though: those tables surface at random moments and vanish just as fast, and no human can sit refreshing OpenTable all day and all night.

Automating the watch

That is the gap SeatSwiper closes. You tell it the Zitz Sum table you actually want, your date range and party size, and it watches that exact table around the clock, then books it the moment one opens, whether that is a fresh weekly release or a last-minute cancellation. The reservation lands on your own OpenTable account, in your name, a completely normal booking with nothing resold. Your first booking is free, and after that it is a flat $5, charged only when it actually gets you the table, with no subscription and nothing owed when it comes up empty. Be clear on the limits: it works on Resy, SevenRooms and OpenTable only, it needs your reservation account connected, and it can lose a race when a single seat is up for grabs, so think of it as a far more patient watcher than any person, never a guarantee.
