How to Get a Reservation at Grill 23 & Bar (Boston)
George Yates · Founder, SeatSwiper · Updated August 15, 2026
Grill 23 & Bar is Boston’s original power steakhouse, open since 1983 inside the landmark former Salada Tea building at 161 Berkeley Street in the Back Bay. Beneath soaring marble columns, dark mahogany paneling, and a coffered ceiling, it serves dry-aged prime beef, a raw bar and seafood tower, and one of the deepest wine lists in the city. It is the room Boston books for anniversaries, closing dinners, graduation weekends, and any night that needs to feel like an occasion, which is exactly why a good table here can be hard to lock down. Here is how the reservations actually work and how to get one.
How booking works at Grill 23 & Bar
Grill 23 takes its reservations on OpenTable, both through the OpenTable app and the booking widget on grill23.com. Service is dinner only, starting at 5:00 pm, so every seat the restaurant has each night is a dinner seat, which concentrates demand into a narrow band of prime evening times.
The booking calendar runs on a rolling window, so new dates generally become available roughly a month ahead rather than in one big yearly release. If you have a fixed date in mind, the safest move is to reserve as soon as that date rolls into range and appears on the calendar. Grill 23 does not usually ask for a deposit or a card to hold a standard two- or four-top, though larger parties and the private dining rooms are handled separately and can carry their own terms, so confirm the details when you book.

Why a Grill 23 table books out
A few things stack up against you. Grill 23 is dinner only, with no lunch service to soak up demand, so the whole fight is over evening tables. Its Back Bay address sits in the middle of the hotel, theatre, and business district, which keeps weeknights busy with expense-account dinners on top of weekend celebrations. The 7:00 to 8:00 pm prime window and Friday and Saturday nights are the first to fill.
Then there is Boston’s calendar. Graduation season across the city’s colleges in May and June, Valentine’s Day, Restaurant Week, and the winter holidays all turn an already popular steakhouse into one of the hardest tables in Boston, in the same tier as tough rooms like Krasi. If you are flexible on time and day, though, you have far more room to work with than the prime-time crowd fighting over the same handful of slots.
Off-peak and back-door ways in
You do not have to win the Saturday-at-7:30 lottery to eat here. Grill 23 has more ways in than most special-occasion rooms:
- The bar and lounge. The first-floor bar serves the full menu and takes walk-ins, so a solo diner or a pair can often eat the same steaks with no reservation at all. See whether hard restaurants take walk-ins.
- Early and late seatings. A 5:00 or 5:30 pm table, or anything after 9:00 pm on a weeknight, is far easier to grab than the 7:30 pm peak.
- Weeknights over weekends. Monday through Wednesday are the quietest nights, and the room and the kitchen are exactly the same.
- Smaller parties. Two-tops turn over faster and open up more often than tables for six or eight, so book the couple’s reservation and add seats by calling if plans grow.
- Off-season windows. Deep January and late summer, away from graduations and holidays, are the softest stretches on the calendar.
When cancelled tables reappear
The other way in is patience. Boston plans change constantly, and a business dinner or celebration that falls through puts a prime Grill 23 table back on OpenTable, often within the last day or two before the reservation, sometimes the same afternoon.
These returned tables can appear and vanish in minutes as the next person grabs them, which is why refreshing the app on and off rarely lands the good ones. If you understand the restaurant’s cancellation rhythm, you can aim your attention at the windows when seats are most likely to reopen instead of checking at random.
Set the watch and stop refreshing
Watching a single steakhouse calendar by hand is a grind, especially when the table you want is a Friday two months out that only ever opens for a few minutes when someone else lets it go. That is the part worth handing off.
Automating the watch
That is where SeatSwiper comes in. You tell it the Grill 23 & Bar table you actually want, your date range and party size, and it watches that table on OpenTable around the clock, then books it the moment one opens, whether that is brand-new availability or a seat someone just gave up. It reserves on your own account, in your own name, so nothing is resold and you simply show up to dinner. Your first booking is free, and after that it is a flat $5 only when it actually gets you the table, with no subscription. To be straight about the limits: it works on Resy, SevenRooms, and OpenTable only, it needs your reservation account connected, and because a single returned seat can come down to a race, it is a far better watcher than any human but never a guarantee.

FAQ
Does Grill 23 & Bar take walk-ins?
Yes, at the bar. The first-floor bar and lounge serve the full dinner menu on a first-come basis, so even when the dining room is fully booked you can often walk in for a steak, especially early in the evening or on a weeknight. The reserved dining room is a different story and fills well ahead.
Does Grill 23 serve lunch?
No. Grill 23 is dinner only, opening at 5:00 pm every day, so there is no midday seating to fall back on. That is part of why evening tables are so competitive, since every reservation is fighting for the same dinner hours.
How far ahead should I book Grill 23 & Bar?
For a weekend or a special occasion, reserve as far ahead as the OpenTable calendar allows, generally about a month out, and grab your date the day it appears. Weeknight and early-evening tables can often be found much closer in.
Is there a dress code at Grill 23?
Grill 23 leans smart and business-casual, in keeping with its clubby, old-Boston room, though it is not a jackets-required steakhouse. When in doubt, dress up rather than down, and call ahead if you want to confirm for a specific event or a private room.
What is the best night to get a table at Grill 23?
Monday through Wednesday are the easiest, and an early 5:00 to 5:30 pm seating or a later post-9:00 pm one opens up the most room. Save your flexibility for those windows if you are booking on short notice.
