Bistro L'Ancêtre
603 rue des Ursulines
Oddly enough, this is the only restaurant on Ursulines, tucked away in a suitably old building at the far east end, but it draws a local crowd in addition to tourists. The food is more Italian than French, with pizzas and pastas making up most of the menu, but all mains include soup, dessert and coffee and cost only $7-12.

Great downtown location, but watch out for stinging wasps, if you dine on the patio!
