There are four really good Mexican restaurants in Highland Park. I can highly recommend Antojitos Chilangos, El Huarache, Le Abeja and Metro Balderas.
Here on Orange County, I can recommend Carnitas Los Reyes,, Taco Mesa (calamari!), Tacos Jaliscq, Taqueria El Granjenal, Taqueria Mexico, Taqueria Morelos and Tom's Tacos.
