We live in La Crescenta and as many poeple know there is a drought of good food up there.
There is a truck run by a nice family that parks in the AUTOZONE parking lot in tujunga. It has about the best Asada and El Pastor tacos and burritos I have had!!!!
*bonus* their larocco pupusas are awesome as well (you need to ask for extra cabbage)
I have tried all the taco stands (broncos - Tortas de mexico - los burritos - chicken shack + more) around the area and this truck is by far the best!!
