Patty Slaps draws a wide range of reviews, with many calling it among the best burger spots in Montreal thanks to juicy smash patties, bold toppings and tasty fries, while others find it pricey or a bit greasy and smoky for some diners. The self-serve ordering and quick service are frequent positives, but several visits note inconsistency in quality, longer waits during peak times, and a strong oil smell in the dining room. The vibe is described as cool and industrial, with occasional praise for vegetarian options and poutine, and multiple comments say the burgers stay flavorful and satisfying even when delivery experiences vary. Overall, Patty Slaps emerges as a must-try for burger lovers, valued for quality and atmosphere even as prices and some aspects of execution spark debate.View restaurant profile
