Jennifer Garner and Ben Affleck met up with Matt Damon and his pregnant wife, Luciana, at Nobu Malibu on Saturday night for a two-hour dinner on the patio that included cooked fish and sushi rolls.

“Ben and Matt were entertaining the girls with stories, and they were all laughing a lot,” says an observer of the couples.

When dessert came, the celebratory group toasted – after all, Garner and Affleck’s third wedding anniversary was the following day.

“Jen and Ben were in a great mood, and they left Nobu hand in hand,” says the observer. Also spotted at Nobu Saturday night: Kate Hudson, back in L.A. following last week’s Santa Barbara getaway with Lance Armstrong.
