Where Jay-Z eats, the masses follow. So it is at Lucali, Mark Iacono's heralded pizzeria in Carroll Gardens that has earned as much ink for its artisanal pies as for its famous fans. This week the cultish joint opens a spin-off in Sunset Park, helmed by Iacono's brother Chris. The 40-seat eatery offers an identical menu of classic calzones and thin-crust pizzas. As at the original, guests can watch flour-dusted chefs punch and pull mounds of dough in front of a wood-fired oven. But drinkers, take heart: Unlike BYOB Lucali, Giuseppina will serve beer and wine.
