Had the fish machaca, which was spicy / flavorful / different but not too hot and was good, and the serving was generous. They also had cooked (griddle?) whole jalapeños in the salsa bar, which is always appreciated.
The corn tortillas (which I like) ended up a bit soggy, which is due to the nature of the fish & veg filling, but doubled tortillas would be a good solution. Also, the rice appeared to be steamed and was OK, which is lighter, but is not Mexican. My buddy had carne asada, which he said was good.
