Mercury Chophouse – Arlington serves prime rib as a Friday and Saturday feature through the end of September: a 14 oz Prime Rib Dinner with creamy mashed potatoes, au jus and whipped horseradish crème for $50, available while supplies last. It is a seasonal run, not a year-round item, and it returns as a special from time to time; ask your server or check the current menu on the website to confirm it is running. On other nights, the Bone-In Ribeye at $90 is the closest cut.
Seasonal item. Prime rib is a seasonal Friday and Saturday feature, not a year-round item, so it is not available every night. Ask your server, or check the current menu at mercurychophouse.com, before you plan a visit around it.

Prime Rib Nights: what, when and how much
Mercury’s own announcement is short and worth quoting in substance: Prime Rib Nights return to Friday and Saturday nights this August and September. A 14 oz Prime Rib Dinner is served with creamy mashed potatoes, rich au jus and whipped horseradish crème for $50, available while supplies last.
| Detail | Prime Rib Nights, 2026 |
|---|---|
| Nights | Friday and Saturday |
| Run | Through September 30, 2026 |
| Cut | 14 oz prime rib |
| Plate | Creamy mashed potatoes, au jus, whipped horseradish crème |
| Price | $50 |
| Availability | While supplies last each night |
At $50 with the potatoes on the plate, it is the least expensive full beef dinner on the ninth floor during its run, well below the 6 oz filet at $62 that anchors the standing steak list.
Prime rib is not a ribeye, and why that matters
Prime rib and ribeye come from the same section of the animal, the rib primal. The difference is the cooking. A ribeye is cut into a steak first and grilled hard and fast. Prime rib is roasted whole, slowly, as a large bone-in roast, and sliced to order after it rests. The result is a softer, more evenly pink slice with a thin seasoned crust on the outside edge and the juices collected as au jus.
That is why prime rib is a feature rather than a nightly item. A roast has to be cooked as a whole and sold the same evening, which is what while supplies last means in practice. When the last slice is gone, the kitchen does not put another roast in, and the table moves on to the standing menu. The horseradish crème is the traditional partner because the roast is milder than a grilled steak and takes to a sharp condiment.
How to make sure you get a slice
Book early in the evening. Friday service runs 11 AM to 10 PM and Saturday runs 4 PM to 10 PM, and the roast is finite. A 5:30 or 6 PM reservation on either night is the safest way to be seated while the prime rib is still being carved. Mention it when you book, ask your server, check the current menu on the website, or call 817-381-1157 on the day and ask whether the roast is on.
The feature is not printed on the July 2026 dinner menu, so ask your server for it by name. Parties of six or more carry a 20% gratuity, and the standard sides and starters are all available alongside it: a Wedge at $18 before, Creamed Spinach at $16 to share, and the Crème Brûlée at $15 after. Free garage and outdoor parking is at the Brookhollow Two tower on E Lamar Blvd; the parking page explains how it works on game nights.
A Friday or Saturday in the district
The two nights the prime rib runs are the two busiest nights in the Arlington Entertainment District, and Mercury’s location on E Lamar Blvd, north of the stadium lots, makes it the easier dinner on either. Globe Life Field is about a mile away, AT&T Stadium about a mile and a half, and a Saturday concert or a Friday Rangers game does not close the roads to the tower.
The sun sets at about 8:15 PM in August and 7:35 PM in September, and the main dining room’s curved window wall faces west and southwest over the district. A 6 PM prime rib dinner in late August puts the slice on the table with the sun still up and dessert arriving as the lights come on at Six Flags.
Prime rib the rest of the year
Outside that run, prime rib is not on the standing menu. It returns as a special from time to time, and the restaurant does not publish dates in advance. The closest thing on the standing menu is the Bone-In Ribeye at $90 with Dijon butter, which is the same rib primal cooked as a steak; the Bone-In Ribeye page covers it. For a slow-cooked beef plate with jus and whipped potatoes, the Braised Bone-In Beef Short Rib at $82 is the year-round answer.
Every seasonal feature, including prime rib, lamb, lobster tail and shrimp and grits, is tracked on the seasonal menu page. If prime rib is the reason for a private dinner, the Boardroom seats 8 to 20 and private menus can be tailored; submit the request through the event inquiry form with the date and the dish, and the team responds within 48 hours.

Frequently asked questions
What nights is prime rib served at Mercury Chophouse?
Friday and Saturday nights during the August through September 2026 run of Prime Rib Nights. The 14 oz Prime Rib Dinner is $50 with creamy mashed potatoes, au jus and whipped horseradish crème, and it is served while supplies last each evening. It is not served on other nights.
How much is the prime rib dinner at Mercury Chophouse?
$50 for a 14 oz cut with creamy mashed potatoes, rich au jus and whipped horseradish crème on the plate. Other sides, starters and desserts are extra and priced from the standard menu. Parties of six or more have a 20% gratuity added.
Does the prime rib sell out?
It can. The announcement says the dinner is available while supplies last, which reflects that a prime rib roast is cooked whole and carved to order until it is gone. An early reservation, around 5:30 or 6 PM on Friday or Saturday, gives the best chance of being seated while it is still being served.
Is prime rib available year-round in Arlington at Mercury?
No. Prime rib is a seasonal feature, run as Prime Rib Nights through the end of September 2026. Outside that window the Bone-In Ribeye at $90 is the nearest cut, since it comes from the same rib section cooked as a steak. The Braised Bone-In Beef Short Rib at $82 is the year-round slow-cooked beef plate.
Can I get the prime rib at lunch on Friday?
Prime Rib Nights is an evening feature. Friday lunch runs from 11 AM with the weekday lunch menu, which includes the Hand-Cut Ribeye at $67 and the Bone-In Ribeye at $82. To be safe, ask when you book; the restaurant does not publish the exact hour the feature begins.
