Grab a gargantuan slice at this popular take-out joint, or order whole pies in the small, adjacent no-frills dining room. In the wee hours, lines often snake out the door for the artichoke-spinach slice, which tastes like cheesy dip on thick, crusty crackers. Those in the know opt for the less greasy margherita slice. Make sure you're hungry, and be prepared to stand in line a while. For shorter lines, stop into the Greenwich Village location at 111 MacDougal Street. Or try the more formal Artichoke outpost underneath the High Line at 114 10th Avenue.
