I'm not keen on going club hopping night after night, but I will tell you Club 88 is top-notch when talking about the Chengdu array of clubs and bars stretching from the North train station all the way down to the American Consulate and the South side of the city. 88 is extremely happening, pretty much every night of the week. The best bar about it is, it is next to around 4 rival clubs, so if you get bored of one, you can go to the next bar and so on.
1. Did not exit the bar alone. Their have been reported cases of attacks, and I know that when hundreds of drunk men are club hopping, it is good to stay within a group.
2. If you want to go, tell the taxi driver ba1si2ba1 (Local Sichuan Hua for "88"), and they will all know how to get there.
