Problem is you spend you hard earned money to go, thinking it will be an exhibition of belly dancing, as we first did only to find it is not. So, now we DO choose not to go to any belly dancing and have done for years now.
It is a shame, but there is no way of knowing whether you will see a real belly dancing exhibition or not.
It was unfortunate that at the last BBQ in the Istanbul they had a belly dancer and we did not know she was going to be there. We watched her trying to drag men up from the next table to us and they did not want to go, one guy got very angry with her. It IMHO better for the girl to ask for volunteers to participate.
I have only every spoken to one man who enjoyed this entertainment and that was Highlander. I would also think that the lovely Brenda was a million times nicer than a belly dancer.
