It's tiny, charming, and utterly fabulous. You could also say it's cramped, crowded, and utterly fabulous.
It may be you've walked past it during your adventures in the Plateau, although a line-up usually marks this corner. This little hole-in-the-wall doesn't seat more than a handful of people and the menu is en français. But Quebecois or not, the two guys behind the counter will feed you good food; the best of which are in bite-size portions - mini burgers! You can dress the beef burger any way you want but the fish burger is a house specialty. The condiments are homemade and you can taste it. Their poutine got my stamp of approval - hot savoury gravy atop nicely fried potatoes and cheese curds. All you need is a couple of bucks. Crazy.
You may encounter a bit of a wait, but be patient for the front of the line is just two bites to food heaven.
