It's time for a regional taco tour! Comedians Carlos Ballarta and Jesus Trejo go on an epic food crawl with "Taco Scholar" Bill Esparza to try two specialties: Nayarit whole-hog tacos and Pueblan pit-roasted lamb barbacoa. And when we say special, we mean special. Los Sabrosos Al Horno is the only taquería in L.A. where you can get crispy suckling pig nestled between a tortilla and topped with a unique mustard salsa. At Barba Kush, lamb skulls and offal are cooked underground in a backyard, using time-honored techniques from Puebla. Get ready for the feast of a lifetime!
