Overall :
Mache! was a perfect lunch on a rainy day. The food, service, and prices were great and our meal lasted just long enough to pass the storm. Normally I'd say it's not worth going out of your way for BUT as I mention below, the poutine was enough to knock it up to 5 stars!
Food :
My partner and I split an order of the poutine, which was the single best "traditional" poutine we had while in Montreal. The gravy was perfect and there was just enough cheese. We both tried the shepherd's pie (which was labeled in a way I think translates to Chinese pie?) I had the Trio which was so delicious - the meat was spiced perfectly, it didn't need even a pinch of salt. The potato was enough to compliment the flavor without overwhelming it. My partner had the vegetarian pie which she really enjoyed. She commented on the texture and the inclusion of eggplant with skin, and after trying some I'll say it was pretty good. Boreale on tap isn't uncommon in Montreal, but it was perfect to round out the meal.
Service :
Our waiter was really friendly, moreso than most anyone else who served us in Montreal. He chatted with us a little near the end and he answered our questions really well, and overall was obviously concerned that we have a good time.
Decor / Price :
I thought the decor for Mache! was cute. I really liked the blackboard menu and as I remember there was some really nifty lighting inside on the side wall. I also want to comment that of everywhere we ate in Montreal this place was the cheapest, for what ended up being a lot of food!
