Reviews describe B12 Burger as offering huge portions, juicy burgers, and a halal friendly menu with many guests calling it among the best burger spots in Montreal, though experiences vary by location. The positives emphasize generous burgers, fresh toppings, crispy in house fries, and friendly, attentive service, with staff often praised for warmth and efficiency. A number of criticisms point to overcooked or cold fries, inconsistent doneness of meat, and sauces not always matching requests, along with occasional long waits and slower service during busy times. Cleanliness and ambiance receive mixed notes, ranging from clean and welcoming to areas that could be cleaner, and there is often no self serve sauces you have to ask. Parking and noise can be challenging depending on location, and price is sometimes cited as high for the portion size, though many feel the value is good. Some reviewers mention favorites like the B Overdoze or trio meals and insist the burgers are delicious, while others note flavor differences between branches such as Laval and Acadie. Overall the consensus is that B12 Burger is a solid, satisfying option with large portions and a generally positive service experience, but results vary by location and moment.
