Mâche was a highlight of my Montréal trip. We were searching for a place and decided to take an Urban Spoon recommendation and was pleasantly surprised by the whole experience. The place was well designed, the menu was quiet extensive, and the food was great. I had la boule (parmesan meatball with tomato sauce) and la "p'tite vie"(shepards pie with ground beef, corn, and mashed potatoes). Both were great. On top of everything my bill came up to $15.
If you are looking for somewhere easy, nice, but cheap I would check this place out.
