The Mansion opened in 2012 as a venue/hub for musicians, artists and other young "creatives." Most people know it for their weekend nights, when the basement and ground floor transform into a nightclub hosting local DJs playing everything from techno and deep house to hip hop. It's a popular place, especially with a younger, foreign crowd, models, and various weirdos and transient characters ready to dance all night. They also have a backyard with a pool and a beach, where they host events in the warmer months. Important: After 10pm, the entrance to the Mansion is ON Yan'an Lu, after Hongjing Lu. Stay far to the right and you'll see a little "secret" door. There might even be some other taxis and street food vendors there. This place goes very late on Friday and Saturday -- like, 8am -- so it's often an after-hours end up.
