The Silver Kris Lounge in SIN T3 is miles ahead of QF's business lounge in SYD, but way behind their F lounge there. You need to compare apples with apples. And apart from the overcrowding issues I'm not sure that the offering in the NH, JL and even CX lounges at their hub for their business class lounge is all that different to what SQ offer at SIN.

Even in SIN, you can't compare the QF First Lounge (when @TheRealBabushka mentioned the comparison, being a OWE I assume they were talking about the QF F lounge not the J lounge). But I'd say the QF J lounge in SIN (to compare like for like) is on a par with or behind the T3 Silver Kris Lounge. It started with a bang, but it can also be a zoo at the wrong time and has certainly been "enhanced" since they opened the F lounge.

Now as for the F lounge, I think it is behind some of the other F lounges. I mean it's a great place for free hawker food. But seriously SQ need to realise whilst it's nice to showcase hawker food, they could offer a bit more (and I count the burgers as hawker food too, there's a couple of really good hawkers doing burgers these days). In the old incarnation of the F lounge, I remember the lamb shanks and dishes like that they used to offer, but now it's basically just cooked to order hawker food. If you're an airline that has 19-20 flights a day to Australia, a similar number to Europe, up to 10 a day to Japan, you should to offer more than just local food.
