Restaurant Grégoire: a true snack-bar institution

In Mercier, on Montreal’s South Shore, the name Grégoire means far more than just a restaurant – it’s a genuine institution. Open since 1945, this family-run snack bar has, over the decades, become a must for lovers of classic Québec comfort food. Here, the most iconic dishes of our culinary heritage are served with unwavering consistency and generosity: overflowing poutines, perfectly stacked burgers, grilled hot dogs—you name it.

Among the house favorites, the all-dressed burger stands out for its balance. A soft bun toasted on the grill, a juicy patty, crisp lettuce, fresh tomato, crunchy red onions, pickles, and a slightly sweet house sauce that ties it all together.

Of course, there’s one thing for which Grégoire is famous throughout the region: its poutine. Here, there’s no fooling around when it comes to portions or quality—fries are cut in-house, golden and crispy just right; the cheese curds are fresh, served in slices rather than crumbles (a unique touch that makes each bite especially melty and even); and the brown, homemade, slightly spiced gravy makes their poutine one of the best in Québec. For the more adventurous (or simply hungrier!) there’s another must-try: the poutine bun. Picture a generous serving of poutine tucked inside a hot dog bun—savory, melty, indulgent. Yes, it’s filling, but oh, it’s good!

What makes Grégoire even more endearing is its story. Opened more than 80 years ago, the restaurant is now run by the third generation of the family, who work to preserve its soul while meeting today’s customer expectations. Despite its growing popularity and busier pace, the original spirit remains intact. The staff is warm, and orders are taken with care.

Because you love poutine. Because you’re looking for an all-dressed burger that tastes “just like the old days,” only better. Because you’re craving a true Québec snack-bar experience. Grégoire is the place you go back to when you want food that feels like home—only extra delicious. No wonder we think it’s among the best snack bars in the province!
