B12 Burger specializes in the preparation of premium beef patties and crispy fried chicken, focusing on delivering high-quality textures through precise cooking techniques. The menu centers on thick, juicy burger configurations layered with fresh toppings, artisanal sauces, and toasted buns that maintain structural integrity. Fried chicken offerings provide a significant contrast, featuring a seasoned, crunchy exterior that yields to tender meat. The kitchen prioritizes bold, savory flavor profiles that define the core of casual handheld cuisine. Patrons find a streamlined selection that highlights core ingredients rather than unnecessary complexity. Every item served reflects a commitment to classic preparation methods favored by those seeking substantial, hearty portions in a consistent, straightforward environment. The establishment maintains a sharp focus on the integrity of its primary menu staples.
B12 Burger is widely celebrated for its massive, flavor-packed portions and high-quality, fresh ingredients, making it a top-tier destination for burger enthusiasts in Montreal. Patrons consistently praise the juicy, well-seasoned patties and a diverse menu that includes creative options like the Overdose and buffalo chicken burgers alongside classic choices. While the food and hospitable service are frequently described as excellent and worth the price, some visitors note that the restaurant space can feel small and crowded, especially during peak hours. Long wait times are sometimes expected due to the made-to-order preparation, yet the overall consensus highlights a satisfying, filling, and memorable culinary experience that encourages many customers to return.
I live in Ottawa & each time I go to Montreal, visiting a B12 branch is a must. I am simply in love with their burgers. I truly hope they open up a branch in Ottawa soon with the same quality & quantity. I have visited different locations of B12 over the last year & this one stands out for sure. Great service & delicious burgers, I especially love the overfose & buffalo chicken burgers. Fries are crispy & tasty, the chips are always cold, I hope they serve them warm or hot if possible & also the soft drinks fountain is not good, drinks from it are watered too much, I would recommend buying bottled drinks instead.
I've had a consistently bad experience at B12, & this last visit was the final straw. They often get my order wrong, so this time I specifically asked the employee to double-check before handing it to me. He confirmed that it was correct.
When I got home, the order was not only completely wrong, but honestly disgusting. I had clearly asked for meat, & instead I received a spicy chicken dish that I could barely eat. The only reason I forced myself to eat some of it was because I was starving.
If mistakes happened once in a while, I'd understand. But when wrong orders are frequent & staff reassurance turns out to be unreliable, that's a serious problem. I won't be coming back unless there's a clear improvement in accuracy & quality.
Honest solid fast-food joint that really doesn't feel fast-food anymore once you start eating the food. I'm serious, I had to pinch myself when my number was called for 2 reasons: my name was called (properly!) & the tray of food I was receiving didn't look like what you'd get these days for 20 bucks. I thought it would be all filler & no substance, but I was wrong again. Khalil expertly recommended that if I really want a chicken burger with some kick, that I should go with the Buffalo chicken burger. Glad I listened to him! Not only was his recommendation spot-on, but the burger was big, satisfying, filled with fresh ingredients (shredded carrots, banana peppers & coleslaw) that add crunch (but also tortilla chips!) & was truly flavor packed... I'm writing this now, wishing I had another one, honestly! The chips are a must though. Freshly made in-house they come as homemade chips & fries, & they are copious & hard to resist. I left there, appreciative, full & happy, something that I can rarely say these days about most restaurants I visit. Considering that was a better burger than most burgers I've eaten in the last year, some at twice the price of this one, I'll be back the very next time I have a hankering. You don't find value like this at many places anymore, so I guess that makes this a top-shelf find! Show up hungry & expectant, you won't be disappointed...

I had the B12 Burger Classic, complete with the B12 sauce, lettuce, tomatoes, pickles, a 200-gram Angus beef patty, bacon, onion rings, & cheese sauce. This burger was so immense that I had to slice it in half. It was incredibly juicy, with the B12 sauce overflowing. I've never had a burger quite like it before, & it left a lasting impression. I paired it with poutine as my side dish, which was also massive. My eyes & stomach weren't in sync, & the meal could easily have fed two people. Finishing it was a struggle, & I remained pleasantly full for the entire day.
My wife, on the other hand, ordered the Swiss Chicken Burger with a side of fries. The Swiss Chicken Burger featured pesto sauce, arugula, tomatoes, grilled chicken, Swiss cheese, caramelized onions, & caramelized mushrooms. She thoroughly enjoyed her burger, which, like mine, required both hands to handle. The fries were wonderfully crispy & tasty.
In addition to burgers, they also offer hot dogs, but their in-house submarine sandwiches outshine the typical submarine sandwich makers. Their extensive menu includes mini burgers, nachos, poutines, Mac & Cheetos, chicken tenders, & even salads. B12 Burger caters to everyone's tastes. This isn't your run-of-the-mill burger joint; it's a culinary experience your stomach won't soon forget. @mtlrestorap
The burgers are HUGE & the buns are super soft. The fries & onions rings are amazing & the nachos are crisp & savory! Love this place! Great menu that doesn't have just burgers -- great for little ones that are picky eaters. You're spoiled for choice. It's real food too -- not processed stuff. Like the popcorn chicken was actually chicken breast. It's stick-to-your-ribs type of food. The staff are really nice as well. Went more than a few times & always something we haven't tried.
