Date night!

Brad Pitt and Angelina Jolie left their six kids behind at their Paris hotel on Wednesday night. The couple -- in town while Jolie, 34, shoots scenes for The Tourist -- headed out to the restaurant at Hotel Costes for an intimate one-on-one dinner.

"They had bodyguards and not many people noticed," a restaurant staffer tells The couple "held hands" as they made their way to a private, secluded table.

Clad in jeans, Pitt, 46, pulled out Jolie's chair as they sat down. ("She was wearing a casual outfit with her hair down," the observer says.)

Think Jolie ordered a light salad? Think again: the staffer tells Us she dined on medium-rare rib-eye steak with sauteed leeks. Pitt's meal, meanwhile, included roasted potatoes with truffles; the pair shared a bottle of red Bordeaux wine.

The happy twosome "enjoyed their meal" and chatted "the whole time" during their 90 minute feast, the Hotel Costes employee says. "They just had their moment ...together," the staffer adds. "You can't see anything negative between them."
