This trip, Guy's getting an authentic taste of all ends of the earth. In Bakersfield, Calif., the firehouse-turned-restaurant firing up Latin-fusion favorites like basque lamb tacos and popcorn pork with a side of zing. In Northfield, N.J., a Sicilian spot servin' all kinds of authentic specialties like grandma's pizza and homemade pappardelle pasta. And in Phoenix, the funky Thai joint dishing out off-the-hook dumplings and coconut Asian pork.
