I just ran a search on here and found a post from 2009... but nothing really since then.
I initially started searching for "LA mexican hot dogs" because of the hand cart wielding ladies who pop up after a show in LA at a place like the Palladium. As far as I know after Googling, they're Sonoran style. Bacon wrapped with mayonnaise and guacamole, assorted other condiments.
Given Austin's large Mexican population, I'm shocked I haven't seen these amazing dogs here. That said, I haven't tried too hard looking. Have any of y'all run into anyone who serves these dogs in town?
