Frank Bonanno doesn't cook anything that's not memorable. What's more, he's fearless. And Luca's menu is designed for gluttonous abandon, arranged for wild flights of pairing and sharing, set up in an attempt to make people eat the way the Italians do — with several courses of small plates leading up to the entrees. The portions are small, the combinations divine, and while you may get lucky and hit some of the best choices following the old app-entree-dessert structure, it works better just to eat and keep eating until you can't hold any more.
