Prime Bar à Boeuf at Royalmount in Montreal draws praise for a smash burger cooked to perfection with a juicy patty and a mouthwatering brioche bun, complemented by sauces that elevate the bite; the poutine is a frequent highlight for its rich gravy and cheese curds, sometimes with tender pulled beef, while fries are hit or miss depending on the dish. The chicken sandwich and Caesar salad are well regarded for seasoning and freshness, though the salad can disappoint on occasion. Service is consistently described as friendly and attentive in the food court setting, with staff explaining options and going the extra mile. Prices skew higher for a counter service, but many feel the quality justifies it, with several reviewers calling it among the best burgers in Montreal and a standout in the Royalmount area. Overall the menu emphasizes high quality ingredients and solid execution, making it a popular choice for lunch or dinner despite some inconsistency with fries and salads.
Smash burger: Crispy-edged, juicy-centered AAA Angus beef, dripping with melted cheese & layered with caramelized onions, fresh lettuce, pickles, & that rich, tangy house sauce.
Golden fries on the side, hot, salty, impossible to resist & a chilled glass of bubbly to lift every bite. It's indulgent, it's messy, it's exactly what you want right now. #PRIMEBARABOEUF #Montreal
The smash burger at Prime Bar à Boeuf in Royalmount, Montreal is cooked to perfection, with the potato brioche bun also hitting the mark. The lettuce still feels unnecessary, but the burger itself is juicy & flavorful.
The fries have been hit or miss in our experience, but they truly shine in a poutine. The last time we visited, the poutine was excellent. The sauce is rich & tasty, the cheese is just right, & the aioli on the side is a nice touch.
The service at this food court counter was excellent. Our server was friendly, professional, & engaging without being overbearing. He even took the time to speak kindly with my child, which was really appreciated.
Of course, it's still a food court, so you carry your own tray & find your own table. But for what it is, Prime Bar à Boeuf delivers a satisfying burger experience & attentive service that goes above what you might expect from counter service.

This has to be the best burger I have had in a long time. The temperature was spot on, their sauce was magnificent, & the fries were a perfect side. It was my first visit, so the staff took the time to explain the various options & guided me perfectly. A must-try, if you're in the area. Actually, it's even worth a detour!
I just looooove this place!! The food is tasty; you pay for quality. Hands down one of the best burger i had; it was juicy, the bun was crispy on the outside & soft on the inside & their sauce is simply delicious. The chicken sandwich is very well seasoned & very juicy while still being crispy, & the caesar salad is a big portion & you can taste that it is homemade sauce with fresh lettuce. I feel like all their ingredients are quality, especially the meats.
The staff is great, always smiling & i never had any mistakes made with my order.
Top notch beef quality with great ingredients used. They certainly don't cut down on quality. This is not your average hole in wall burger joint. You cannot pass on the Roast Beef sandwich if you do love roast beef. The black garlic sauce of the Wagyu burger is absolutely phenomenal. Safe to say they have the best burgers in Montreal! The service is fast & great as well, special mention to Mike. The team will accommodate you to their best ability. Out of all places of the mall, this is where you'd want to go. I certainly will be coming back many times to come!

Pathetic service, we ordered a prime rib sandwich no sauce. After putting sauce on the first try, the cook was so distracted talking that he put sauce on the second sandwich & tried to clean it off without me noticing. Absolutrly pathetic. Go to the taco place beside them. Much bette
