My first time J class to HK visiting the three lounges, The Wing, The Pier, Quantas. The best lounge, providing you don't have a short connection time, is by far Quantas. The food and service was excellent and not crowded like The Pier and The Wing. I suppose the Quantas Lounge is some sort of hidden gem, Also the lounge is nice and bright with nice views to the adjacent gate. I found the Pier too dark, also kids yelling and running around don't add to the atmosphere. JMHO.
