After reading about this place on the "cheap eats in calgary" thread, we decided to make the trek (for us). Definitely worth the trip: for us, the best Mexican we've found in Calgary(not, though, like saying "the best Mexican food in L.A."). And for about half the price--for $20 we got 2 tacos, a tostado, and an enchilida combo.
We ate in the restaurant, and right now, it's a pretty desolate space with very little furniture (some tables and very rickety stools), but it looks like they haven't finished the renos. My other suggestion would be for them to include some homemade salsas (ah, the salsa bars of the SF taquerias). But even as it is, it fulfilled our craving for decent-to-good Mexican food in this town. I hope other people will find their way over--it was pretty empty when we got there (in the middle of the afternoon, admittedly), and I'd hate to see them not make a success of it. It's at 10015 Oakfield Drive SW (238-1749).
