Having just come down stairs from that lounge I have to agree with all your comments tuapekastar.
.... and they do now serve Moet & Chandon.
Thats great news if it is a permanent change. I gave feedback to them last year that the offering, while good and at least equal to other Conrad's, was significantly below that of comparably priced 5 star chains in Singapore. With the Westing coming online soonish they would need to make those small changes to offer a truly excellent experience.
I also found the lounge a bit small but the Pan Pacific was closed for renovations at the time.
