Alberto's

Covina, CA
all damned night!
This is a chain and there are a few in So. Calif. (4-5 that I've eaten at so far)
It's a fast food type place with home made tasting mexican food. They're taquitos (called rolled tacos on tyeir menu) are delicious!! Also their chile relleno burrito is yummy too! The food is always great and even better late night.
