Lan Kwai Fong is a real place in Hong Kong where bars and clubs are located.  喜愛夜蒲3 (Lan Kwai Fong 3) (Blu-ray release 2014-2-19) repeats the same formula that made the series commercially successful: Many beautiful women, several sex scenes, many bodies to see but no nudity, a few comedic moments, and several shallow love stories.  Apparently the filmmakers fully understand showing enough flesh is sufficient to make money for a low-budget movie, regardless of the stories (I suppose the same rule applies to porn).  There is no originality to be found in this installment, other than a ridiculous act by a man to convince a woman to love him at the end.
