My wife and enjoyed Casa Azteca during an afternoon when we were between appointments, and found it quite satisfying. The service was quick and polite, and their food was definitely of home cooked quality. We chose to enjoy their taco buffet. It was fresh, hot, and had a flavor unique to the location. The spicy sweetness of the enchiladas blended... More

Visited Casa Azteca not too long ago. The service was a little slow, but staff polite and nice. The food was hot and edible, and the price not to steep.

Thought the fact that it was busy for lunch on a weekday was a good sign...then saw the buffet. Reasonably priced buffet is a perfect place for a hungry worker to grab a quick lunch. We ordered off the menu and the service was quick; but the food was just OK. Atmosphere was also nothing special; though service was efficient.

We were greeted promptly and seated with our menus. The hostess asked if we wanted the smorgasbord which included some Mexican items but as we were there a while the popular item seemed to be fried chicken. We both ordered enchilada plates from the menu. Neither of us finished our full meal. Needless to say this is a pass for... More
