We love Casa Fiesta! The food is great and service is always fast. We've never had to wait for seating. I always get the chicken chimichangas with beans and rice. Their guacamole is very good but I've had better salsa. I don't like very much cilantro in my salsa and they use a lot but that's okay. The servers are always very curtious. It is located right off of Stringtown Rd. in Grove City.
