I heard very good things about asada fries from my (other) native sources. Only so many days so many calories :-).
I am also on the fence about nachos generally. They can be really really great but so many factors in play. Chip type foremost. I think they are also “hard to teach” in a restaurant setting because too much of X, Y, Z and the balance is off. Would have to do everything by scoops… carne asada fries remove the chip type variation.
