The Bull Moose Chicago Reservations: How to Get a Table

Climb the stairs at 2020 N Halsted, past the noise of Beaumont’s tavern on the ground floor, and you arrive somewhere that feels like it was airlifted out of 1955. The Bull Moose occupies the second storey of an 1890s building that used to hold two apartments, and the owners kept the domestic scale on purpose: two fireplaces, big tufted booths, a little bar, lighting kept low enough that you squint at the wine list. Their own description of it is a Manhattan of a room, dark and brooding and rich, named after a grandfather who stood a little taller, liked his steak rare and drank his bourbon neat. The kitchen dry ages and butchers whole sides of beef in house, and the dry aged cuts are built for two people to share: a 23 ounce bone in New York strip, a 26 ounce bone in ribeye, and the house specialty, a 32 ounce porterhouse. Every steak and chop arrives with a soup or a salad and the signature Robouchon potatoes. It is a small room doing a very specific thing extremely well, which is exactly the recipe for a book that closes fast. Here is how to actually get into it, verified against the restaurant’s own pages in September 2026.

The one detail that changes your whole approach

Most Chicago steakhouses hand you a safety net: the bar is walk in only, so a full calendar never means a locked door. Beaumont’s downstairs works precisely that way, with a big central bar you can turn up to and grab a burger at. The Bull Moose does not. Its reservations page says plainly that all tables and bar stools are made available for reservations, which means the stools you would normally treat as your backup plan are sitting in the same OpenTable inventory as the booths. Walk ins are welcome, and the restaurant says so, but it also says walk in availability may be limited, and now you know why. On a busy Friday there is no reserve pool of unbookable seats waiting for you. Whatever the online calendar shows is very close to the whole picture of the room. That single policy line is the reason the strategy here is booking rather than turning up hopefully, and it is the detail almost every roundup about this place leaves out.

The 21 day rolling window

The restaurant states that reservations are available on a 21 day, rolling basis, and the booking itself runs through OpenTable, embedded directly into thebullmoosechicago.com rather than sitting on a separate venue portal. Rolling is the operative word. There is no weekly batch and no published hour when the calendar advances. Each day, one new date enters range at the far edge of the window, so a Saturday you want becomes reservable exactly 21 days before it happens and not a minute earlier. That makes the planning arithmetic trivial. Take your target date, count back three weeks, and put a reminder on that morning. Because no fixed release hour is published, treat it as an early morning job rather than a midnight alarm: open the calendar first thing, see whether your date has appeared, and take it if it has. If you want to sanity check the window yourself rather than trust any guide including this one, the honest method is to open the OpenTable calendar, scroll to the furthest date that will still load, and count the days between that edge and today. That distance is the live window. The general theory of how these windows behave, and why a three week runway behaves so differently from a two month one, is in how far in advance you can book.

Five nights, shared steaks, and six seats

Three separate things compress the supply here, and they compound. The first is the schedule: The Bull Moose serves Wednesday through Sunday, opening at 5pm midweek, 4pm on Friday and Sunday, and 3pm on Saturday. Monday and Tuesday it is dark, so a full week of Lincoln Park demand has to squeeze into five services instead of seven. The second is the food itself. When the marquee cuts are 23, 26 and 32 ounce steaks intended to be shared, and every one of them comes with a soup or salad course, tables turn slowly. A booth that takes a porterhouse is occupied for the long haul, not the ninety minutes a quicker room would flip. The third is size. Press coverage of the opening put the upstairs room at roughly 76 seats, and the restaurant itself simply calls it small and cozy. Multiply a small room by five nights by slow turns and the prime block, roughly 6:30 to 8pm on Friday and Saturday, is gone almost as soon as it becomes reservable.

Party size is a hard ceiling online

The reservations page is direct about it: at the moment they are taking reservations for up to six guests. That is not a soft preference, it is what the booking widget will accept, and there is currently no private events path to route a bigger group through either. The private dining page says they are not yet booking private events and are collecting enquiries until packages and pricing are finalised. So if you are seven or more, the realistic options are splitting into two bookings on the same night or waiting for the events programme to launch. Phones are staffed during business hours only and the restaurant strongly encourages booking online, so calling to negotiate a larger table is a slow road rather than a shortcut. The upside of the six person cap is that it pushes almost all inventory into twos and fours, and a two top is both the most plentiful configuration and the one most likely to reappear when someone gives a table back.

Where the returned tables come from

The Bull Moose does not publish a deposit or a cancellation fee on its own site, so whatever terms apply are the ones shown on the OpenTable confirmation screen when you book. What that absence tells you is useful: with no punishing fee forcing everyone to release at one tidy deadline, returned seats do not bunch up at a predictable hour. They trickle. In practice the richest stretch is the 24 to 72 hours before service, when the week firms up and speculative bookings get released, with a second smaller wave on the day itself as parties shrink or reschedule. OpenTable returns a cancelled table to public inventory the moment it is given up, which means a sold out Saturday is genuinely not a closed door, it is just a door that opens at an hour nobody can predict. The catch is that a freed seat is visible to everybody at once and goes to whoever confirms first, and in a room this small the good ones last minutes.

The play

• Count back 21 days and be there that morning. Logged into OpenTable, party size set, card saved. For a Friday or Saturday this is the single highest leverage action available to you.
• Book Wednesday, Thursday or Sunday if the date is flexible. The same kitchen, the same fireplaces, a fraction of the competition. Sunday closes at 10pm, so the late slots there are the softest seats of the week.
• Take the shoulders. Saturday service starts at 3pm and Friday at 4pm, which is genuinely early for a steakhouse and reliably under-booked. A 4pm porterhouse is still a porterhouse.
• Book for two. The steaks are designed for two, the two top is the most common table, and it is by far the most common cancellation.
• Do not count on the bar. Those stools are in the book. Walking in is worth a try on a quiet Wednesday and is a poor plan on a Saturday.
• For how this sits against the rest of the city, the Chicago hard-tables guide has the landscape. Bavette’s Bar & Boeuf runs the same 21 day depth with the opposite mechanic, a synchronized 9am Resy opening, and Maple & Ash is the third Chicago steakhouse booking pattern again.

Automating the watch

Both paths above come down to the same thing: being in front of the calendar at the exact moment a seat exists. One of those moments is predictable, the morning your date crosses into the 21 day window. The other is not, because a cancelled booth can come back at 11pm on a Tuesday. That is a job for software rather than a person refreshing OpenTable between meetings. SeatSwiper watches the exact Bull Moose table you want, your date range and party size, on OpenTable around the clock, and books it the instant one appears, whether that is new availability or somebody cancelling. It books on your own OpenTable account, in your own name, for your own dinner. Nothing is resold or transferred. The first booking is free, then it is a flat $5 and only when it actually gets you the table, with no subscription; if you want it standing watch on a specific sold out night for a cancellation, starting that watch is $1. Two honest limits worth knowing: it works on Resy, SevenRooms and OpenTable only, and it can lose a race for a single hot seat, so it is a far better watcher than any human but never a guarantee. Set it once, and spend the three weeks thinking about the porterhouse instead of the calendar.
