Rhiannon asked me to let you know she's going to be late back from the wedding as they were late getting there (inherited her mother's sense of direction sadly!!! ) but she'll put the answer up and tonight's question as soon as she gets home.
The answer was: Rendez-vous des Stars in the Studios. This caught a few people out, in fact several people seemed to think it was the Hotel New York. I can see why because of the decor but I assure you it's Rendez-vous des Stars!
