One of mine was the Gardens of Taxco on Santa Monica Boulevard in West Hollywood. They had delicious Margaritas and it was hip, with lots of actors and musicians. Ha ha!
Some of you may say La Chiquita on East Valencia in Fullerton, or Las Perlas near Maple Elementary School.
I remember a lot of people liked El Cholo on Whittier Boulevard in La Habra. The El Cholo on South Western in LA was always popular, especially with college students. Much later El Cholo in Irvine opened.
I forget the name of the old Mexican restaurant in Placentia, the one that’s been there for generations. People love it and mention how the lady owner used to be strict with them!
I like El Moreno's in Orange on East Chapman, where you can sit outside in the patio under oak trees (and pigeons).
Of course, El Adobe in San Juan Capistrano is a legendary place, and I know a lot of Lancers still go there. It was said to be Richard Nixon’s favorite restaurant.
There was Cano’s Mexican Seafood on PCH in Newport for a while, around the 1970s.
There was a legendary old place called La Fonda on Wilshire Boulevard just west of Downtown. Of course a lot of us went to restaurants in Olvera Street when we were children.
