Finally made it out to Oakwood to try out Mi Tierra Tu Taqueria. They have closed the grocery to make room for a larger restaurant. I would say that this is the best Mexican food in Calgary. I had chicken enchiladas with verde sauce (served with rice & beans) and my husband had the choriqueso tacos. Both dishes were excellent and very tasty. Both were spiced well without being too hot (though it might be too hot if you don't like spicy food....we love spicy!).
The owner waited on us and the service was attentive and quick. We will definitely be back. Also, they are planning on opening another location at Heritage and McLeod that will have a liquor license.
