Maybe slightly of topic because I observed this about two years ago when were last in Restaurant of the Stars. The restaurant was closing at I think, 4pm and I noticed the man sitting at the table next to us leave to go out side and use the toilet, at least he was heading in that direction. When he returned a cm had locked the door because the restaurant was closing, so he couldn't get back in to finish his meal, he knocked on the door but it was left to a customer to let him back in. The restaurant really should have been built with a toilet, but as it wasn't whoever was in charge should have thought of this. Maybe they do now this was sometime ago. I've never had any trouble with the restaurant, we had booked and we went to the top of the queue and a cm lead us to our table, however I wouldn't go in near closing time in case I needed to leave, I might not be able to get back in.
