Is this the satellite terminal lounge at KUL?
I found it ok for 2 longish stopovers. I am from PER and the PER QP is my regular haunt so lounges don't need to be great to beat it.
I found they had a decent food selection, with pasta, soup, multiple other hot dishes, desserts, icecream and a continental selection as well as a salad station.
The Internet was fine once I got into it but some areas don't seem covered by the wifi properly. The lockers are useful too, keeping stuff safe without lugging it around the terminal.
Maybe I'm talking about the wrong lounge, or haven't experienced a properly decent lounge yet!
