Born in Lynwood, California, Glen Bell graduated from San Bernardino High School in 1941. He served in the U.S. Marine Corps as a cook during World War II. After the Marines he started his first hot dog stand 'Bell's Drive-In', in San Bernardino in 1948. In 1952, he sold the hot dog stand and built a second location selling hot dogs and hamburgers. He soon started selling tacos at a taco stand named Taco-Tia at 19 cents each from a side window. Between 1954 and 1955, he opened three Taco Tias in the San Bernardino area, eventually selling those restaurants and opening four El Tacos with a partner in the Long Beach area.
