Patty Slaps is widely praised for juicy smash burgers and creative toppings, with many reviews highlighting favorites like a bacon driven burger and a mushroom or truffle option, the pretzel bun adding a distinctive bite, and the poutine a strong side. The burgers are described as flavor packed and fresh, often with a balance of toppings and a bun that holds up well, while some diners find portions small for the price and a few burgers a touch greasy. The fries receive mixed notes, ranging from crispy and tasty to disappointing when not hot or soggy, and some reviews mention that the poutine can be salty. The self service ordering kiosks and fast service are consistently seen as convenient, though a few comments point to busy periods causing longer waits or louder ambience. The atmosphere is repeatedly labeled stylish, energetic, and casual, with mural art and a beer friendly vibe, yet a handful of reviews note variable staff experiences and occasional language or accessibility hiccups. Overall, Patty Slaps stands out as a premier burger spot in Montreal, delivering top quality beef, bold flavors, and a strong sense of place, with some concerns about price, portion size, and occasional inconsistency.View restaurant profile
