I find it just ok. I'd give it a 2.5 if I could but definitely not a 3, so...2 it is. By just ok I mean that you won't feel hungry afterwards nor feel sick, you won't need to frown when eating those tacos but won't remember what they taste like as soon as you're done with your meal. There's nothing special to it, the tortillas seem to be store bought and sauces pre made and watery like almost every other Mexican place in Montreal...
Or maybe I'm just being picky having lived in Mexico for many years...
