The lunch line can be long at this aromatic Italian market, but it gives you ample opportunity to size up the day's offerings. Conservatives may go for the greaseless, cheese-laden plain, for instance. Adventurers will probably zero in on trendy items like the Mexican pie, bejeweled with circlets of yellow pepper. And traditionalists may well seek out the saucy black-olive-and-mushroom version, sleek with olive-oily goodness. But while the toppings may differ, all of Gallucci's pies have much in common, including their thick, yeasty, and miraculously crisp-edged crusts.
