In QF lounge. Arrived about 7:30 am. Airport quiet as was lounge then got busy for about an hour and quiet now as planes depart. When asked was offered fizz, Pomeroy and I think Krug.
I very much doubt there was Krug in the QF lounge. SQ serves Krug onboard in F class only. The only time I've seen Krug in a lounge was briefly in SQ's private room during a special promotion. Even back in the day (over 15 years ago) when SQ F lounge had decent bubbles it was only Dom not Krug.
