Il Sole is certainly competing with Mr. Chow's to be the most celebrity studded restaurant in the city! The quietly popular hot spot saw a trio of ladies this Sunday night, starting with Rumer Willis - in a cute hat - and a lovely and gracious Jewel, who posed with a few fans and her favorite cowboy! The night ended with a frantic Nicky Hilton exiting the restaurant, dodging questions about sister Paris (and her impersonator) before jogging to her car and driving off with boyfriend David Katzenberg. Why all the fuss, Nicky?
