I love El Taco! I've been going to the one on Florence for about a decade. It isn't an authentic taco stand type place though. Although, really good americanized mexican food. I like their Carne Asada Burrito, Chile Verde and Flautas/Taquitos.
I've been going to the El Taco on Firestone for about 30 yrs and occasionally to the one on Florence and the Firestone location is much better. One reason is the cooks at Firestone have been there forever and they are more concerned about the finished product. Same Owner.
