Guy Fieri's firing up an entire world of barbecue, from smokin' chicken salad in Delaware to Argentinian flavor in San Diego and a traditional Hawaiian pig roast down in the ground in Kauai.

Tuétana Taquería / Mar Rustico (San Diego, Calif.) • Shawarma Guys (San Diego, Calif.) • Donabe Asian Kitchen (Taos, N.M.)

This trip, Guy's jumpin' into a full culinary adventure. In Old Town San Diego, with a two-for-one spot servin' Baja-style seafood and rich bone marrow tacos. Stayin' in San Diego, a funky Middle Eastern food truck puttin' out next-level shawarma rated best in the U.S.A. And in New Mexico, a pan-Asian joint pullin' out the all stops with curry noodles and a bison Reuben bánh mì.
