I used to literally work next door to Las Fuentes (in the valley on vanowen/reseda i beleive). The food there was great. Super salsa bar and the food was always delicious.
Moved back to LA and now go to Paco's Tacos (both locations) all the time. The fresh tortillas cant be beat, food is great, and service is always very nice.
I would actually have to lean towards Las Fuentes if i had to choose.
