Chez Tousignant is a great lunch spot close to Jan Talon market. There's hot dogs, burgers, and poutine, and that's about it. That being said, the food is top shelf. Hot Dogs are home-made, and maybe the best I've had. The burgers are great too, especially the Tousignant burger with maple bacon. Their homemade donuts are pretty good too.
The only downside are the fries. They're too starchy and not crispy enough. Not sure if it's an issue with frying temperature or the type of potato but the fries were the only thing keeping this from a 5 star review.
