We've been on the hunt for a good taco place in montreal for a couple of years now and basically settled with matraca and taco Tijuana because we couldn't find anything better. But both places are a bit overpriced and limited in other ways as well.
Azteca, on the other hand was perfect! Four tacos for $5 and you can mix and match. (That's half the price of the other two places and tacos were delicious!) Plus they have other specials depending on the day (e.g., $1 tacos), and offer other food (like enchiladas, burritos, tortas and quesadillas) but we might always come here on Fridays because the special that day is mole enchilada (emmoladas)! I cannot tell you how much I love that rich, sweet, chocolatey/spicy sauce on my enchiladas and the portion was huge. Total for a very filling dinner for two with tax and tip was about $30. Nice interior, too.
Seems to be a local favourite because it was quite busy. I'm surprised there are not more rave reviews!
