The pair left after an hour of booze-fueled PDA and they were careful to keep their distance before leaving in separate vehicles.
At the time, Cage — who has a child with Kim named Kal-El — had been promoting his action thriller, Dog Eat Dog, with co-star Willem Dafoe.
According to sources, Kim regularly meets Foglietti at the late-night haunt, which is close to his home.
Rumblings about their close friendship began in February when a cryptic comment posted by “Carlswife” appeared beneath an article about the Moonstruck. star on Las Vegas Weekly’s website.
The post, which has since been deleted, said, “His wife Alice Kim has been cheating on him with Carl Foglietti, manager of Grape Street Café in downtown Summerlin. He also sleeps in Queensridge where Nick (sic) resides with his family when Nick is out of town for projects.”
