An Italian family-owned cruise line, Silversea ensures that cruisers can indulge in pizza 24/7. Midday at La Terrazza, pick from 10 different pies cooked to order, plus two that rock the buffet. (And, of course, you can customize any pizza.) The crisp 10inch pies come with sophisticated toppings. I adore the Piccante; it’s topped with ’ nduja, a spreadable spicy Calabrian sausage that’s so on trend today.
