I last did MAS F a couple of years back, on the A380 from KUL to LHR. The food was virtually identical to biz class and was ok, nothing special. Seat was good, I was the only person in F and had a window seat made up as my sleeping seat while I ate, drank and watched movies in the seat next to it. KUL F lounge was nothing special to me but I am not a lounge conisseur I try to arrive at the airport as late as possible. I did note there was a smoking section in there and the staff were super great about keeping me informed when the flight had a minor delay.
