Was able to visit the lounge on my trip out on March-6.
I have to say, the new F lounge are quite stunning and the dining room concept had very good service by the staff on hand. I highly recommend the Johor Laksa (local Msian, the sauce was thick and rich) when available. One gripe is that they do not have a drinks menu and everything has to be told to you by your server.
As for the smoking lounge, it is shared with the Business class side, go to the back through the door and it will be to your left.
