On this trip, Guy Fieri's grabbing a little surf, turf and flavors from the earth. In San Juan, Puerto Rico, a local gem is serving regional favorites, like off-the-hook pork trifongo and shrimp empanadas. In Somerville, N.J., a funky spot is firin' up a something-for-everyone menu, including righteous vegan dishes like a mushroom po' boy and a meatless turkey club. And in Cleveland, a Mediterranean hot spot is servin' outrageous octopus and masterful lamb, beef and ricotta meatballs.
