Also enjoying a guys' night out: Benji
and Joel Madden
. The brothers were enjoying dinner with friends at Katsuya Hollywood in a very large booth, and, an observer says, "It seemed as though they ordered everything on the menu!" Also at the sushi spot that night: Ciara
, who ate in the private Dragon Room behind closed curtains, and Olympian Shaun White
, who feasted on the restaurant's signature dishes.
