Guy Fieri crosses the Atlantic to dive into the many different cuisines of Barcelona. In Saint James Square, a bocadillo shop makin' all sorts of tasty Catalan sandwich specialties. In the Eixample district, an authentic Galician spot craftin' octopus tapas and other comfort food from northwest Spain. And in the Gràcia district, a mom-and-pop joint servin' up old-school Catalan cooking, including snails just like mom used to make.
