Hours after stepping out for a workout – and flashing her wedding ring! – the Oscar winner grabbed Thursday night dinner at Tavern in Brentwood with pal Chelsea Handler, who picked up the actress from her house.
At the restaurant – which is owned by Suzanne Goin, the chef who catered the actress’s wedding – the ladies enjoyed sharing each other’s company. “It was a night of girl talk,” says an onlooker, “[of] chit-chat and catching up.”
But there was also food: Witherspoon ordered fish and a gimlet, and split some spring vegetables with Handler, who also picked up the check.
“Reese was so nice,” the onlooker says, adding that she was in a “good mood, always smiling.” And the women, who costar in the upcoming comedy This Means War, had each other in stitches during their meal.
Says the onlooker: “They had some good laughs together.”
