Best, best tacos in L.A. - Tito's Tacos on Washington Place, in Culver City. Not a chain, but fantastic. I read a review that said they are not "super authentic" and I guess that is true: meat, cheese, lettuce and a fantastic sauce/salsa , and so tasty! There are always lines there, and although we don't live near there, we detour whenever we are nearby. I have met people across L.A. who have been there and love it.
