I had lunch the other day at El Indio in north Redondo Beach.
I got the chicken casadilla diner, and it tasted so good! Well spiced chicken, tender crispy shell, great rice and beans. Authentic? I grew up in Ohio, so I can't say - but wow, it was good.
E Indio is a casual place with a small dining room. There is usually a steady stream of people getting take-out, too.
