Yes. It's not brilliant - but it's not awful. Proper flat beds with mattress toppers, but not very much privacy in a 2-2-2 layout on the A380. Food is decent, but not outstanding. Very similar to QR's 777 J in terms of the hard product, but without quite as much length in the seat.
MH flounge in London is very small, with a reasonable selection. Not tried the biz lounge there. KL lounges are much larger and more spacious.
It's not earth shattering but it's head and shoulders above BA premium economy at the same price, particularly if the BA timings to Bangkok don't suit.
