The message on T.A said "Closed Permanently". Reviews where taken down. There was a message in Turkish from "The Management " that it was now permanently closed.
However, thanks to the members on T.A. Advisor. The restaurant was informed of the news on T.A. So, the Restaurant Page was opened again and reviews can now be added. Seems like someone had been posing as the Management, to get the page closed. Alternatively, perhaps the Management changed their minds and decided to keep the place open?
It may be a good idea if you have a business advertised on T.A with reviews, you should perhaps keep an eye on it to make sure it has not been closed down.
