Zero Zero may be named for the superlative flour used in its blistered pies, but it is so much more than a pizzeria. While the Castro topped with oozing mozzarella and spicy soppressata is delicious, this casual spot offers far more than just a good slice. Absolute knockouts include a beautifully composed panzanella accompanied by basil pesto, as well as gnocchi tossed in a hearty pork belly ragù, decked with dollops of ricotta making it light and bright, despite the indulgent ingredients. A mix of families, hipsters and business folk from the Moscone Center fills the warm, bi-level space. Group dining is ideal for sampling more of the menu, and the sizable bar will ensure that everyone's furnished with a terrific cocktail or pint of local draft root beer.
