Checking in 1 - Sleeping Dogs
Head to the club and talk to the bouncer. Talk your way inside and enter the club. Once inside, head to the VIP room and talk to the bouncer. Find the marked hostess and have her escort you inside the karaoke room. Once inside, sing a song for Tiffany. The karaoke mini-game is simple; you don't have to press any button but you have to move your pointer instead.
After the song, go upstairs. You should find another jade statue by the counter so don't forget to grab it along the way.
Approach Benny to trigger a scene. You have to defeat his bouncers until you finally corner him in the bathroom downstairs.
In addition to the usual Field Report and Cash rewards, you'll also get Tiffany's phone number and unlock new karaoke songs as well. Head to meet Winston for a short scene afterward.
