As with the tacos de trompo at La Macro, these are the real deal. And since Karanchos is an entirely outdoor affair, it's a good thing National Taco Day is in the fall—because you're sitting outside. It's really all the better to bask in the smoky aroma eminating from the trompos as they rotate, and you won't be able to tell if you're sweating because of the weather or the spicy salsas on the al pastor tacos.
