My partner and I went to La Matraca on a Saturday afternoon, and the food and service were amazing. Mind you, the place was pretty dead when we got there and slowly picked up for the dinner rush.
I ordered the marinated pork tacos, as they state that they are known for their tacos, and boy oh boy! As a die-hard Mexican food snob, I'm happy to say that La Matraca is authentic, delicious, and well priced. Quite easily, the best tacos in Montreal.
Forget the imitators, for real tacos, this is the place to beat!
