Del Taco? They started as a small taco stand in Barstow, Called Taco Tia, sold to the Hackbarth brothers in 1964 and chanded the name to Del Taco, named after one of the brothers. Have seen them sprouting up all over the country in the last decade.
FYI just hade a combo burrito at Del Taco in Boise this week, it was nothing like burritos sold at the little taco stand on 1st street in Barstow.
