One of the top-grossing restaurants in the country, and with this location why shouldn’t it be? Right smack up against the Rock Center rink, icy wipeouts enhance your power lunch. Energetic al fresco scene, too. Tourist magnet, priced accordingly. Italian-inflected eats, think fried calamari, roasted fennel risotto, farfalle with shrimp. Clean, modern, corporate feel, i.e. par for the Rock Center course. If the tree’s up, watch out for epic waits.
