I love this place. It's legit SoCal style (coming from someone that's lived there and has had real Mexican tacos).
The octopus taco really surprised me as I'm not usually a fan of the texture and tends to be very chewy when cooked elsewhere. However, they make it right here. It's very soft and blends in very well with the sauce and pumpkin seeds. A definite recommend!
I've also tried La Carnita and Grand Electric. They are awesome in their own right but if you want real authentic, down and dirty Mexican-SoCal tacos this is the place to be.
This place is not a good dine-in. They have seats but very limited, maybe 6-7 indoor and 4 outdoor. Great take-out option.
Also making it a goal to try every item on the menu. Two tacos will fill me up good. Three would be pushing it. So far, I've tried the octopus taco and baja fish. They also have daily specials (they go real fast!).
