I availed the Golden Lounge yesterday. It was not easy to locate, with very poor signage. I went up the elevator to where it looked like there were some lounges, then asked staff who guided me. I was travelling OneWorld J.
Bar stools, relaxing chairs and dining tables. Staff were very active, but seemed jaded and were not friendly. No greetings, no offering of anything.
Lounge was very busy (mainly it seemed full of Australian voices). There was a very limited range of soft drinks + free access to bean-to-cup coffee machine. Alcohol was in a separate 'bar' room which had a nice view of the tarmac (but no food) and you had to fetch your own wine etc from that room and carry it, then put it down and fetch your own food.
Wide variety of foods on offer, some hot dishes, desserts and salad bar already made + a noodle bar with 3 x recipes made to your order.
Bathrooms (bizarrely hot) and quiet rest rooms - shared by gender. 2 massage chairs to try which I could not get to work - you needed to use an app.
View of some planes on the tarmac. Strange acoustics meant it was very difficult to find a quiet area, despite screens between chairs. I could hear in detail all the conversations loudly of whichever person was sitting fairly near me, as if they were immediately next to my head.
I would not rush back, but it was pleasant enough for a couple of hours.
