This is not the most authentic local restaurant in San Diego. However, the food is better than average, and what really sets this place apart are the hours of operation. Taco Fiesta is open 24 hours a day, making it readily available whenever you have a Mexican craving that needs to be satisfied. The simple foods are the best here; things like hard shell tacos and chicken burritos. The meats are fresh, however, I'd stay away from the pork entrees. I've found the meat to be tough and old tasting.
