Overall, reviews describe B12 Burger as known for gigantic, juicy burgers with generous portions in a casual setting, offering a strong value and plenty of menu variety including halal options in some locations. Many praise fresh ingredients, bold flavors, and satisfying meals, along with generally friendly service, but several notes mention slower service during busy times and occasional quality fluctuations such as bread that is stale or patties that are bland, and fries that are not always ideal. The size of the burgers is a common talking point, with many diners leaving full and returning for the experience, while a few feel some dishes are overpriced or could be improved. Still, the consensus leans toward a go to spot for a memorable burger meal with generous portions, solid taste, and a lively atmosphere.
Je suis tombée en amour avec les burgers de B12 Burgers ! 🍔
Ils sont vraiment sains, frais & pleins de saveur. On sent la qualité des ingrédients dès la première bouchée.
Le service est agréable & l'ambiance est super aussi. Franchement, c'est une excellente adresse pour manger un bon burger sans culpabiliser.
One of the best fast food chains in Canada & it deserves well the 5 stars because of what it has to offer! Highly recommend trying it if your on a empty stomach
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.

Franchement, B12 Burger, c'est une valeur sûre ! Les burgers sont vraiment incroyables : la viande est super juteuse, bien goûteuse, & les ingrédients sont frais du début à la fin. Chaque burger est bien monté, généreux, & on sent que c'est fait avec soin. Les frites sont excellentes aussi, bien croustillantes, parfaites pour accompagner le burger.
Le service est rapide & super sympathique, le staff est accueillant & prend le temps avec les clients, ce qui rend l'expérience encore meilleure. L'ambiance est chill & conviviale, parfaite pour aller manger entre amis ou juste se faire plaisir après une grosse journée.
Honnêtement, si t'aimes les bons burgers, B12 Burger vaut vraiment le détour. J'y suis allé une fois & j'ai déjà envie d'y retourner. Je recommande à 100 % ! 🍔🔥
I was served quickly, the food is good, but it's really big for one person; I feel like there are too many potatoes. They should have other options to accompany it. I liked it, & that's why I recommend it 100%.
Excellent sevice, la nourriture y est très bonne. On est alle un vendredi soir. C'était très très plein & tout était exceptionnel, bravo à toute l'équipe, surtout Mohamed , je recommande vivement cette succursale, bonne continuation à toute l'équipe
Let's get this clear, the burgers are huge! Not so big that one average person can't eat one but it's still bigger than average (we're still taking burgers). I ordered the B12, I'm happy to report it's fantastic! Not overly greasy, the ingredients were fresh, & the sesame seeds on the buns are toasted to perfection. The only thing I would change would be to add a little more salt on the burger patty. No wonder this place is busy even a midnight! Highly recommended.
Thank you staff for cutting my burger into 4 pieces as requested.
