I went back and listened to Rozzie again. She could be mistaken, and certainly mistaken about the name of the place, of course, but she is clearly saying it is not the night he went to Dragon room and was not able to find her. She says on this night he did find her, "She was drunk and partying". Then three more weeks went by before the police were called.
I don't know how to use the quote feature but this is from The World According. Since this is the first that we have heard of this, could this be around the same time George got the gas cans from KC's trunk. Perhaps there was a certain smell that forced the family to check on Caylee. The timing would be about right (just guessing without having exact dates) and why would you expect to find Caylee at a bar. Unless confirming KC was there, not working and no Caylee. This could be some interesting info.
