The first Del Taco opened in 1964 in Barstow, California with a concept that caught on quickly freshly prepared, made to order Mexican/American food, fast service and value. In more than 36 years, Del Taco has grown to become a major player in the Mexican-style quick-service category. With over 400 restaurants across the country, Del Taco is the second largest Mexican/American chain in the United States.
