The famed cabaret club, known for its stage shows performed by nude female dancers, tweeted a shot of Kim taking a selfie with some fans.
Khloé documented the future Mrs. West and her girls' night out, too, Instagramming a sultry photo of herself and Kendall, her fellow "masked crusader," wearing black lace veils covering half their faces.
Khloé also shared a selfie with Kendall, showing both girls in bright red lipstick, and another with her glam squad, thanking "these talented gypsies" [who] make me beautiful [and] make me smile from the inside out!"
Kim's publicist pal Simon Huck shared a sweet snap with Khloé, too, that showed him planting a kiss on the bridesmaid's cheek. "No one better!" he captioned the pic.
Earlier in the evening, Kim and Kanye joined the entire family at Costes restaurant, where the Kardashian-Jenner crew reportedly racked up a 2,400 euro bill (that's $3,282.72).
That's not all that surprising, though, is it, dolls? After all, only the best will do for Kimye's wedding and the celebrations leading up to it!
