Steven Spielberg and DreamWorks’ partner Jeffrey Katzenberg’s 5-year-old submarine-themed restaurant Dive! has gone under. The Century City (CA) eaterie — whose submarine sandwiches, salads and pizzas once attracted the likes of Michelle Pfeiffer, Tom Cruise, Pamela Anderson and Sharon Stone — served its last patron on Sunday. Financial reasons were blamed. (By contrast, the Las Vegas branch of Dive!, on the Strip next to Treasure Island, continues to do well and is remaining open, a manager there named Lisa told PEOPLE Online Sunday.) A Dive! farewell party held last week reportedly was an emotional affair. Spielberg did not attend.
