Echo going into town if that takes the OP's fancy.

I still visit the Wing when at HKG, but it's fallen off it's perch somewhat. The food in the restaurant is notably of lower quality. It's still good, and better than the Flounge at T5 for sure, but it's not what it was. The cabanas are very nice -- if one wants some alone time. No point otherwise. The wifi in the Wing is terrible.

I like the décor of the QF lounge. I don't think the food is as good as the Wing. But the staff are very friendly, and it's typically better situated for BA departures.

Suffice to say, the food in HK itself will blow the Wing and the other lounges out of the water -- without necessarily breaking the bank. A couple of options in the IFC building next to the Airport Express station: "Tasty" for a fantastic won ton noodle soup (nothing like won ton soup outside of HK) and much else besides. Tim Ho Wan in the basement for a 'cheap' 1 Michelin star experience. The pork buns and chicken feet are very good, the rest is good. Service not so good.
