Dave Chang joins Jonathan Gold and others on an all-night taco crawl through LA, which launches Dave and buddy Peter Meehan into parallel explorations of Mexican food, in unsuspecting places (Copenhagen; Philadelphia) and the colorful homeland itself. It's a timely look at immigration, assimilation, and globalism...wrapped in a delicious tortilla.
