People travel from across town for Stefano Calegari's pizza creations like the Greenwich (stilton, mozzarella and port reduction) or other seasonal toppings like zucchini flowers and chicory or even the pancetta and potato. The suppli - the quintessential fried roman rice snack made here with far from classic fillings like amatriciana and the Genovese with a braised meat filling are also the stars of the menu. But mainly they're after one thing: trapizzini. Invented here, this is the genius combination of a tramezzino (sandwich) and pizza. In essence, it's a triangular pizza pocket of light fluffy dough stuffed with everything from tripe to chicken cacciatore. BUS: 3, 23, 75. METRO: Piramide.
