There's no sushi here but this "mozzarella bar" is based on the idea of a sushi bar, with chefs working behind a "mozzarella counter" and the mozzarella platters presented like sushi. Even the decor is modern Japanese minimalism–meets–ancient Roman grandeur. But here the cheese, in all its varieties, is the focus of the dishes: the familiar cow's milk, the delectable water buffalo milk varieties, and the sinfully rich burrata from Puglia (fresh cow's milk mozzarella encasing a creamy center of unspun curds and fresh cream). They're all served with various accompanying cured meats, vegetables, sauces, and breads. An outdoor deck is a great spot for dining alfresco.
