When out-of-town guests insist on a night in the North End, politely redirect them to this impeccable Porter Square spot that outshines tourist-trafficked wannabes. Book the “Pasta Table,” where chef/owner Michael Pagliarini rolls out handmade dough by day and guests gather at night to enjoy a family-style tasting menu that features mushroom-, oxtail- and pancetta-bedecked plates resulting from his labor. Pop a cork. Dig into decadent dolce. North what?
