Just finished the movie. Damn, no nude pics, no topless, no naked ass, etc... As typical of HK movie editing, the scenes are cuts from several places spliced into one scene. There are scenes of Beijing Club, Billion, and Shake Shake clubs.
In a way the movie is quite accurate of the crowds who get a table. If you want to get the type of girls you see in the movie, you have to get a table and buy a lot of alcohol. Many of the tables are reserved by regulars who also bring or call up their favourite posse of girls, girls who don't seem to have the usual daytime jobs, to give the table a great vibe of fun mixed crowd of hot girls and sharp guys.
Sometimes I would see a table full of guys who are not familiar with that particular club. In this situation, the table will send one or two guys into the crowd to snag girls to come sit with them to build up that vibe of a fun table. When it is crowded and one is tired, an offer to sit down and drink is a very attractive offer.
As many of those type of girls are looking for free drinks, you cannot act offended (it is bad form) if she takes her drink and walks off back into the dance floor. You can only hope that she will return after she had already scoped out all the other tables (eligible guys) and returns to you because you are the 'coolest' crowd.
I generally stay away from those girls that you see in the movie as many of them in the Beijing Club and Billion are part of a table posse. They usually 'belong' to the big shot of the table. Some of those big shots are engaged in dodgy activities/or of the jealous types and I don't want to get on the bad side by getting to close with their chicks. Or if they don't belong to a table posse, I can sense they are gold diggers looking to join a table posse.
If you go to Beijing on Tues/Thurs there are more than enough cute, more down to earth girls in the dance floor or standing around the bar for you to attempt to pick up. If you have to go on Fri/Sat, then you will have to be super confident to snag a girl there, it is possible, but hard work with the crappy ratio of guys vs girls.
Once you get a girl to begin chatting/dancing with you, try not to leave her alone unless you are confident she will wait for you as there are always 10 guys (some I know as buds) waiting nearby for a chance to chat her up too.
I advise you bring a trusted wingman just to keep her engaged whenever you go to the toilet.
