best mexican in l.a.
On the Westside, several options stand out:
The Talpa (please note they do not have a liquor license, but do serve Agave Wine margaritas, which actually pack quite a punch)
Both have excellent food...
There's a few other possibilities on the Westside, but the food is not as good as the two aforementioned places:
Gilbert's El Indio
Casa Escobar Wilshire
The food at the above is passable to good, depending on what you get, but both the quality and strength of their margaritas eclipses the food.
