This trip, Guy Fieri's crossing the Atlantic to take a big bite out of Barcelona, Spain. He's diving in to the many different cuisines the city has to offer, from a homey spot serving Galician-style octopus and soup, to a grab-and-go sandwich stop cooking up traditional sausage and sauces. Plus, a family-owned joint puttin' out old-school Catalan cooking, like rabbit and snail specialties.
