Patty Slaps is praised for juicy smash burgers with standout mushroom and truffle variants, well balanced toppings, and pretzel or brioche buns that elevate the flavor, while some reviewers call the fries decent or underwhelming and note that portions can feel small for the price. Delivery orders often arrive tasting delicious, though some say quality deteriorates in transit, and a few dine in experiences mention inconsistent heat and grease, smoke, or a long wait. The ordering experience is modern and efficient thanks to self serve screens, even as some customers find the pace slow during busy periods and a few staff interactions matter. The atmosphere is described as industrial chic, vibrant, and casual, with a dog friendly patio in season and frequent lively vibes. Overall, Patty Slaps frequently lands among Montreal’s top burger spots, with many raving about flavor, freshness, and value, while others feel it is pricey or inconsistent and wish for better ventilation, more generous portions, and steadier service. Still, burgers are widely regarded as outstanding.
Tasty burgers & fries, service is great & the atmosphere of the restaurant is cool. The burgers are just very messy but have a nice smokey taste. Also, there is a lot of smoke coming from the grill & it kind of fills the dining space.

The wife wanted a&w I insisted on slap patty as usual she was right don't get me wrong both are ok but one isn't as greasy or expensive & maybe it's just me but one kind of tasted like propane 🫣
I ordered for delivery on the one night I stayed in. Didn't want to do fast food. & I did upscale restaurants all week. I wanted to try one of the best burgers in Montreal. I read that this is one of them! It was a decent burger.
I've been coming to this place for a while & the food is usually great. That said, dining in is a constant disappointment. The branch is always filled with smoke & a strong unpleasant smell, & we leave with our clothes reeking of food every single time.
While the food is decent for the price, the quality has been inconsistent lately. The buns & sauces are very good, but the patties are often burnt & taste bitter.
The place has a nice vibe & I'd still come back, but there are clear issues that need attention. Also, the chairs are freezing in winter - so cold that it's uncomfortable to even sit on them.
'I tried the truffle mushroom burger & it was absolutely delicious. The patty was juicy & packed with rich, savory umami flavor, while the brioche bun was fresh, soft, & slightly sweet which was perfectly complementing the burger. The seasoning & truffle notes really elevated the overall taste. My only minor critique is that the portion felt a bit small for the price, but the flavor more than made up for it. I'd have this every day if it was cheaper haha. The service was quick & efficient, & the ordering process was smooth & hassle-free. Overall, a very satisfying meal, I would definitely recommend it for anyone looking for a flavorful gourmet burger experience.
I rarely rate 5-stars, especially when I've only experienced a place through delivery.
When you buy a burger for delivery, you expect a certain level of deterioration with the delivery process. As such, these burgers have no business being this delicious after being in a paper bag & a car for as long as they are. Fries are meh, burgers are excellent. I've ordered three times in the last month from there. My new go-to burger place.
