They came, they conquered … but they had nowhere to celebrate.When C.A.A. and I.C.M. moved to Century City earlier this year they found themselves with few local restaurant options at which to flex their expense accounts. But now there’s Craft. The famed steakhouse, with outposts in New York and Las Vegas, opened a Century City branch on July 13, and its setting just screams power dining.” Roomy booths, well-spaced tables and $21 sides of assorted mushrooms all add up to a good deal for tenpercenters. The restaurant only serves dinner right now, but expects to open for lunch come August. Assistants looking to book their boss’s reservation should know that Craft is typically booked about a week in advance.
