Pizzarium, owned by Gabriele Bonci, Rome's most famed pizzaiolo, gets better and more famous with each passing year, but it still occupies the same small storefront is has since opening in 2003. Bonci uses organic stone ground flour, sour dough starter, prolonged leavening and quality toppings to produce quadrilateral works of art. Toppings change regularly and can be quite creative (rabbit, raisins, and fennel greens come to mind), but classics like pizza alle patate (with potato and mozzarella) and pizza rossa (with a rich tomato sauce) are constants. Pizzarium also sells excellent suppli' (fried balls of rice with fillings) and bread.
