T4 Gate 1 lounge is not a particularly pleasant experience and not really worth visiting in my opinion, if it weren't for the fact that there is nowhere pleasant to sit in T4 anywhere, anyway. Better a free drink in a not-so-good environment than an expensive drink in a not-so-good environment.
At least on Christmas day it (hopefully) will not be a zoo there like it has been lately.
I hope they get this lounge sorted out, or I'll be defecting to non-BA/QF for LHR-SYD/BNE/MEL soon.
