I've already checked out most of the nightlife spots worth seeing. Although I have pretty high standards, my line up would consist of Sugar, Club G Plus and Laris.
Sugar has great cocktails and can kill any sugar addict's sweeth tooth with wicked desserts and drinks. After that, the party continues at G Plus, the only proper club in Shanghai in my opinion since they have the best interior, music/sound system, DJ line-up, management and service.
For me, service is definitely something that distinguishes right from wrong and bad venues from the good ones. Sugar and G Plus are high "fives" in my book for their service.
My other favorite place is Laris, especially on martini night. With a great chef running the venue and people that are trying to make your stay there as pleasant as they can, you can't beat it.
