Long ago, Fresno had a Spanish restaurant called "Estradas" and they had, by far, the best salad on a tortilla that they called Tostada Compuesta. Anyway, I've tried a lot of comparable dishes at numerous Mexican restaurants but none have really come close. I think there was a bit of vinegar involved.
For those that remember, have you found anything similiar? As an alternative, does anyone have a favorite from a local menu?
