Across the reviews, B12 Burger is praised for massive, juicy burgers, generous portions, and fresh tasting ingredients, with many noting the beef is flavorful and the fries are a great match, and several mentions of halal options plus strong chicken and veggie choices. The atmosphere is described as lively and welcoming, making it a go to spot for casual meals with friends or family. Service is often fast and friendly, but some reviews flag inconsistent professionalism at the counter and occasional delays during busy periods, along with a few hygiene concerns such as an isolated hair in a burger. A common caveat is that the portions can be so large they feel hard to finish and can be pricey for what is included in some orders, though others see the size and quality as good value. Overall, B12 Burger is considered one of the top burger spots in the area, delivering bold flavors and substantial meals, with further opportunities to tighten service and cleanliness to reach its full potential.
Strongly recommend
One of the best burger spots in Canada. I visit it whenever I come to Montreal & never missed it. My favorite is the jalapeno & the Swiss mushroom.

Les portions sont généreuses & la qualité de la nourriture est excellente. J'ai été agréablement surpris de la grosseur du burger ainsi que de la fraîcheur des ingrédients.
Le mélange frite/chips est une excellente idée. Les frites étaient croustillantes à point & les chips avaient un bon assaisonnement.

There was a bit of a wait. But the food was good & very large burgers.
However, if I'm paying $20 for a double burger, might as well go to Billy K & get two for the same price :D
The food at B12 Burger is very tasty & clearly made with fresh ingredients. The flavors are great, & the quality of the food really stands out. However, the service needs improvement & could be more professional to match the quality of the food. With better service, this place has the potential to be excellent.
J'ai acheté le club burger (plus cher) j'ai cru qu'il allait être plus gros que les autres burgers (vu son prix plus élevé) il était même un peu moins gros , mais il était quand-même bon. J'ai pas sentit ou vu du fromage suisse.
