Prime rib is the slow-roasted king of the steakhouse menu, and in Colorado it still draws a crowd on busy weekend nights. Some places serve it only on certain days, while others build their whole reputation around it.
This list covers seven spots, from a mountain town on Interstate 70 to a Denver landmark lined with mounted game. Each one gives you a different reason to book a table, so save it for your next big dinner plan.
1. MTN Prime, Idaho Springs, CO
Timing matters at this Miner Street steakhouse. Prime rib shows up only on Fridays and Saturdays, so plan your mountain trip around the weekend if that slice is the goal.
MTN Prime sits in Idaho Springs, an old mining town with a compact main street that makes an easy stop off Interstate 70. The building has big windows and a comfortable, casual feel that still works for a date night.
The rest of the menu leans hearty. Look for elk stew, wild game bolognese, bacon wrapped shrimp, surf and turf, and a crab cake BLT, plus bison meatloaf and shepherd’s pie on the comfort side.
Breakfast and brunch run on weekends starting at 9:30 AM, and there is a kids’ menu with high chairs. Saturday evening is the busiest window, so a reservation is a smart move.
Dogs are welcome on the outdoor seating, and paid parking is usually easy to find.
2. Shanahan’s Steakhouse, Denver, CO
Sunday is prime rib day here, and it comes from a special menu built around the classic cut. That makes it a nice way to close out a weekend in the Denver Tech Center area.
Shanahan’s is a dress-up kind of place. The room has leather accents, a fireplace, a lively bar, and a patio, and dinner here typically runs over $100 per person.
Beyond the prime rib, the menu reaches for big plates like the Wagyu ribeye tomahawk and lobster tail. Seafood towers, lobster bisque, French onion soup, and au gratin potatoes round things out, with creme brulee or tuxedo strawberries for dessert.
Reservations are strongly recommended, and there is usually a wait even with one. Tuesday, Thursday, Friday, and Saturday evenings stay packed.
Hours are 5 to 10 PM Monday through Saturday and 5 to 9 PM on Sunday, and valet parking is available.
3. Iron Chest Steakhouse, Poncha Springs, CO
Out where Highway 50 and Highway 285 meet, a small crossroads town holds one of the better prime rib specials in the Arkansas Valley. Iron Chest Steakhouse serves it with au jus, and you can have it topped with caramelized mushrooms and onions.
The kitchen works with Certified Angus Beef and makes many dishes in house. Filet mignon, bison steak, and a steak salad share the menu with trout penne, trout cakes, and chicken parmesan pasta.
I would save this one for a road trip through Salida or Buena Vista country. It opens at noon every day, which makes it a solid lunch stop too.
Friday and Saturday evenings fill up, and reservations are accepted. Parking is free, dogs are allowed on the outdoor seating, and curbside pickup is an option.
Leave room for the carrot cake or a hand pie.
4. The Keg Steakhouse + Bar – Colorado Mills, Lakewood, CO
Shopping at Colorado Mills burns a lot of energy, and The Keg sits right there on West Colfax Drive to fix that. The Classic Prime Rib is the order that keeps regulars coming back.
Yes, it is a chain, but the room does not feel like one. Wood tones, a fireplace, and a polished yet relaxed setup make it work for both birthdays and weeknight dinners.
The prime rib is known for being well trimmed rather than heavy with fat. Other strong picks include the 20 ounce rib steak, top sirloin with bearnaise, the shrimp and scallop Oscar topper, and pistachio crusted king salmon.
For dessert, the Billy Miner Pie is a long-running Keg tradition. Doors open at 4 PM daily, and happy hour food is on offer.
Dinner reservations are recommended, especially Friday and Saturday evenings. Parking is generally plentiful.
5. Mickey’s Top Sirloin, Denver, CO
Not every great prime rib needs white tablecloths. Mickey’s Top Sirloin is a no-frills Western chophouse on North Broadway, and dinner here usually runs $20 to $40 per person.
The prime rib is tender and pairs nicely with lobster if you want to splurge a little. The namesake top sirloin, filets, and fall-off-the-bone ribs hold their own too.
What makes Mickey’s different is the menu range. Italian and Mexican dishes sit next to the steaks, so you will find chips and salsa, taco salad, chicken fried steak, and jalapeno cheese sticks on the same page.
It feels like a neighborhood spot with a long history and staff who keep things friendly. Families are welcome, with a kids’ menu and changing tables.
Friday and Saturday evenings are the busiest. Save room for the World Famous Skillet Cookie, which is big enough to share.
6. Buckhorn Exchange, Denver, CO
Dozens of mounted animals watch over the tables at Buckhorn Exchange, and they are part of the history lesson. Denver’s storied steakhouse on Osage Street treats every dinner like a trip back to the Old West.
The prime rib here is buffalo, not beef. Order it blackened, or try the Buffalo Prime Rib and Salmon combo for a little of both.
Game is the theme across the menu. Elk, yak, ostrich, quail, buffalo tenderloin, and sirloin game tips all make appearances, and a 45 day dry-aged ribeye is there for beef fans.
Curious eaters can try Rocky Mountain oysters, while cautious ones can stick to Gramma Fanny’s pot roast or the famous bean soup. The staff know the building’s story and the menu well.
Reservations are recommended, and there is usually a wait on Friday and Saturday evenings.
7. The Still Whiskey Steaks, Fort Collins, CO
Old Town Fort Collins has plenty of places to eat, but few that put prime rib front and center on College Avenue. The Still lists it among its house specialties, right next to steak tips and the pepper crusted filet with NY strip tips.
The menu stays hearty and a bit playful. The Meat Pile lives up to its name, and elk tenderloin, short ribs, crab cakes, salmon, and the Colorado Burger keep options wide.
Sides are a highlight here, especially loaded baked potatoes and brussels sprouts. Cheesecake is the classic finish.
Dogs are allowed both inside and out, which is rare for a steakhouse. Doors open at noon daily.
Dinner reservations are recommended for Friday and Saturday evenings. Downtown parking can be tricky, so a nearby paid garage may save you a few laps around the block.
