The lovey-dovey duo popped into the venue with a few male pals, and the group was immediately escorted to a private area in the back that was accessible to people with wristbands only.
“They had a table to themselves complete with alcoholic beverages and mixers,” an onlooker tells PEOPLE. “The group seemed really close-knit and comfortable with each other. At the beginning of the night, James and Kimberly were sitting next to each other, but as it went on, James scooted over to talk to his guy friends and Kimberly seemed to blend in perfectly with the rest of the group.”
Of the happily married pair, the source says they “didn’t really show any PDA,” but they just “seemed really cozy and happy to be together.”
At one point, a woman walked around carrying a bag of candy and light-up plastic rings, and Kimberly went for a sweet treat.
“She took a long gummy worm and started eating it,” says the observer. “She made it look very yummy.”
The new spot, co-owned by David Arquette – who was also on hand that night, dressed dapper in a suit – opens to the public on June 29.
