It seems ridiculous that they are so secretive about it. It may be because some people might be put off if they think there's some kind of theme night as they don't like to participate. We're totally opposite lol! If there's fancy dress or theme, we want to be in it, and would like to know before we go so that we can pack accordingly. I might try to email them but, I know from other responses, I doubt they'll be forthcoming with the information.
