Does not having a full last name make securing dinner reservations more difficult? Apparently not for Yeah Yeah Yeahs front lady Karen O and Beastie Boy Mike D, who snagged a table at what one could call the John D. Oyster Bar. Or for Jay-Z, who can probably get into anywhere, ever, including sushi joint 15 East. But the last-named had to eat, too, especially people with surnames like Gosling, Johansson, Gosling, Hartnett, Gosling, and Gosling. Lots more sightings straight ahead.
