At most RC lounges, there are five food presentations per day: breakfast, ("light") lunch, afternoon tea, early evening hot and cold appetizers, and late evening desserts. All self service elegant buffet with a few prepared to order options like an egg station at breakfast. You might have 24/7 access, including cheese and wine in the middle of the night in Hong Kong. The alcohol seems to include wine all day, mixed drinks at cocktail time, and cognac and port late in the evening. Champagne too. If you're around the hotel all day and not a big eater, consider it the full board plan.
