I have been to the movie night a couple of times and it is a great idea sure to attract a crowd given time if something is done about the (usually Chinese) people who insist on talking loudly and ruining the movie for the people who have come to the cafe to watch.Maybe the staff could have a word with them and tell them to either shut up or go downstairs. Can anyone from the cafe respond?

When in Rome,,, I suggest you start talking even louder, wave your arms around a lot and make sure to reveal the plot and/or how good/bad this movie really is. Maybe they'll get the point or maybe you'll get a fat lip,, only one way to be sure.
