Many flock to the iconic Polo Lounge for a low-key—albeit luxe—evening of impeccable fare, enjoying famous dishes like its signature McCarthy salad and Dover sole meunière. But on Sunday night, for the first time ever, the Beverly Hills Hotel outpost of the storied restaurant was transformed into a full nightclub—ready to host a Grammys after-party thrown by Larry Jackson’s gamma.

The affair began to take shape a little after 10:00 p.m., as attendees slowly trickled into the candlelit venue, dressed to the nines. Outside, small groups congregated around heat lamps to ward off the evening chill, sipping on Johnnie Walker specialty cocktails like the Go Go Highball and Black Label Sour. However, the scene flipped around 11:45 p.m. and the space was suddenly packed shoulder-to-shoulder. Everyone was in particularly good spirits, in no small part thanks to crowd-pumping sets from DJ Millie, Ruckus, and Chase B. The menu had partygoers equally satisfied too: Mini burgers, chicken tenders, and fries kept hunger at bay, as did the eatery’s fan-favorite pigs in a blanket.

Lauryn Hill—the icon, the legend, the moment—entered the room around 12.45 a.m. Hot on the heels of her buzzed-about Grammys performance, the singer made the party feel like a family affair, with daughters Selah and Sara Marley in tow. After posing for snaps, Hill—still in the same voluminous Carolina Herrera gown and dazzling diamond choker from earlier—made her way behind the DJ booth. Much to the crowd’s delight, the music powerhouse grabbed a mic and performed time-honored hits like Lost Ones and Ready or Not. Moments later, the room practically erupted when Jamie Foxx joined her to sing Gold Digger.

Hill wasn’t the only Grammys performer to stop by. At 1:15 a.m., Justin Bieber nonchalantly slipped into the bash, swapping his silky boxer shorts for a bright green hoodie and slouchy jeans. At one point, the Skylrk founder posted up at the DJ booth, bopping along to a few of his own hits, including Essence and Sorry. Also among those keeping the dance floor alive until late were supermodel Winnie Harlow, The Kid Laroi, Jermaine Dupri, Kitty Cash, Jhené Aiko, and photographer Tyrell Hampton.
