Stopped by here for lunch and the place was packed. Portions are very generous, and the hot sauce is extremely hot, so I would advise going with the medium or mild salsa.
They don't go much beyond tacos, burritos and quesadillas, but they do have carnitas as one of the fillings and everything tasted fresh. Service is similar to Subway in that you can choose your toppings.
From their website it looks like they're a franchise out of Ontario that has come west, and they have a bunch of other Alberta locations listed as for sale or already sold franchises.
It's definitely a nicer choice than one of those other taco chains, and I can see myself coming back for another meal. A great option for healthier fast food.
