Book Ahead at Delmonico Steakhouse, Las Vegas

Delmonico Steakhouse takes its tables on OpenTable, and that single fact settles most of what people worry about before they book it. OpenTable venues overwhelmingly run a rolling calendar rather than a synchronized morning release, so there is no alarm to set, no famous hour, no refreshing at 10am while the good seats evaporate. A new date simply becomes bookable as the calendar advances toward it. And here is the straight answer to the question you actually came with: no, you do not need to rush. This is a large steakhouse inside one of the biggest resorts on the Strip, serving lunch and dinner, and on an ordinary weeknight a table for two is usually sitting there a week or two out. What is worth booking early is a specific Saturday at a specific hour for a specific occasion, which is a different problem and a much easier one. Verified against the restaurant’s own site, September 2026.

The room is Emeril Lagasse’s, which is why it does not taste like the other twenty steakhouses within walking distance. He built it at 3355 Las Vegas Boulevard South, inside The Venetian, and ran his New Orleans instincts through the format: Creole seasoning and French technique over aged beef, chateaubriand carved for two, apple-smoked chops, crab-stuffed lobster, Alaskan halibut. The wine program is the other reason it fills up. Delmonico has held Wine Spectator’s Grand Award continuously since 2004, a tier fewer than a hundred restaurants on earth occupy, so the list is a genuine cellar rather than a page of familiar labels. Lunch runs 11:30am to 2:00pm, dinner 5:00pm to 10:00pm, and the house number is (702) 414-3737. A carving trolley and a serious cellar under one roof is exactly why people pick it for an anniversary instead of somewhere trendier.

How far ahead the book opens

Because it is an OpenTable house, the mechanics are the calm kind. Each restaurant on that platform configures its own booking window, meaning the number of days into the future it will accept an online reservation, and most let that window roll forward a day at a time instead of dropping a whole month at once. The full explanation of that machinery lives in when OpenTable releases reservations, and the useful summary is that nothing about it rewards being awake early.

We could not confirm Delmonico’s exact window length from first-party sources, so here is the thirty second way to read it yourself, which is more reliable anyway because a house can change the setting whenever it likes. Open the booking calendar, page forward until the dates stop being selectable, and note the last one that is. The gap between today and that date is the window. Count the same number of days back from your night and you have the morning it first becomes bookable. For most Strip restaurants that horizon sits between one and three months out, and the advice barely changes across that range: if your night is inside the window, book it today. If it is beyond, diarise the day it comes into range and forget about it until then. The long-range version of this arithmetic is in how to book a table months in advance.

Which seatings go first

Availability here is not evenly distributed, and knowing where it concentrates is most of the advantage. The genuinely competitive slots are narrow:

• Friday and Saturday, roughly 6:30pm to 8:30pm. This is the block everybody wants and the only part of an ordinary week that behaves like a hard restaurant. If your occasion is fixed to a Saturday at eight, treat that as the scarce thing and claim it as early as the calendar allows.
• Convention weeks. The Venetian adjoins one of the largest expo complexes in the country, and when a major show is in town every steakhouse on the property fills with expense accounts, at lunch as well as dinner. January is the worst of it. If your trip overlaps a big show, book like it is a holiday weekend.
• The obvious calendar spikes. New Year’s Eve, Valentine’s Day, Mother’s Day, the Formula 1 race weekend in November, graduation season in May, and any night with a title fight on the Strip. These book further ahead than anything else and they are the only dates where waiting genuinely costs you.
• Everything else is negotiable. A Tuesday or Wednesday dinner, an early 5:00pm or 5:30pm seating on any night, and the entire lunch service are consistently the easiest seats in the building. Lunch in particular is the most underrated move here, because it is the same kitchen and the same cellar at a fraction of the competition.

If you want a sense of where Delmonico sits against the genuinely difficult end of this city, the hardest restaurants to book in Las Vegas guide is the honest comparison. Delmonico is not on that end of the spectrum, and a page pretending otherwise would be selling you something.

Party size and where the online widget stops

This is where most people wrongly conclude the restaurant is full. Booking widgets cap the party size selector, commonly at six or eight, and past that cap the calendar tends to show nothing rather than explain why. A blank grid reads as sold out. It usually is not. The online tool has run out of what it may sell you, while the restaurant can very likely seat your group.

We could not verify Delmonico’s exact online maximum, so test it: set the selector to your real number and see whether the date turns empty, then drop it by one or two and watch the times reappear. That tells you the problem is the cap, not the restaurant. At that point the phone is the correct tool, not a workaround. Call the restaurant on (702) 414-3737, or the resort reservations line on 866.659.9643, and say the date, the time and the headcount. Delmonico runs private dining, described by the restaurant as covering everything from business meetings and milestones to first dates and birthdays, so a group of ten or twelve is squarely normal business here. Phoning has a second benefit for an occasion: you can flag the anniversary, ask about the chateaubriand for the table, or arrange a cake while a person is already on the line. More on that in planning an anniversary dinner reservation.

If your date is already gone

Say you tried, and the Saturday you need shows nothing at seven or eight. Work through these in order, because the first three solve it more often than people expect.

Widen the time before you widen anything else. A 5:30pm seating on the date you want beats the perfect hour on the wrong night, and early tables at a steakhouse are unhurried rather than rushed. Then shrink the party if you can, since a six-top is genuinely harder than a four-top on a Saturday and the grid shows you the difference immediately. Then call: the widget sells a slice of the room, the host sells the room, and a phone call gets you onto a waitlist no website will offer. Only after those should you move the date.

The other real path is a cancellation. A Saturday claimed two months ago for a trip that later changed shape is exactly the kind of table that comes back, and Strip restaurants see a lot of that, because the booking is attached to travel plans that move. Returns tend to arrive unpredictably across the final week rather than clustering at one deadline, the normal pattern when no large deposit forces everyone to cancel by the same hour; the general shape is in restaurant cancellation policies. Check your date morning and evening over the last few days and you will catch more than you would guess. Confirm the current terms on the booking page when you reserve, since resort restaurants revise them for peak dates.

Book it once, then let something else watch

Almost everything above is a one-time job. Pick the date, claim whatever time exists, phone in the headcount if the widget balks, and the evening is settled. The task that never finishes is the upgrade: you hold the 5:30pm, you would rather have 7:30pm, and the only way that seat becomes yours is being the person looking in the hour someone hands it back. SeatSwiper watches OpenTable, Resy and SevenRooms for the exact table you describe, and books it the second one opens, on your own account and in your own name, nothing resold or transferred. The first booking is free, then a flat $5 charged only when it lands you a table; starting a watch on a date that is already full costs $1. The honest limits are those three platforms only, and it can lose a race for a single seat. For a restaurant in Delmonico’s position that is the right use of it: you are not fighting for entry, you are quietly trading up a table you already hold.
