HI, I'm sure that this has been covered in great detail in the past, but I'm having trouble with the Chowhound search engine and am looking for a really good Mexican restaurant on the East side for tonight. Doesnt have to be fancy like La Serenata..., clean and decent inside would be perfect. One thought: La Taquiza near USC or La Parrilla in E LA (havent been to either but both are said to be good). Any thoughts? Thanks very much!
