The key to this place is the Lake of Dreams. Instead getting to the lounge and sitting inside, get an outdoor seat and stay to watch the performance of the magic bubble.
Drinks are expensive but strong. You get what you pay for here. The escalators are on a curve which makes it interesting. But kitchy. It's really the show on the lake that you are there for. If you aren't going to see the show, you might as well go to a liquor store, buy some booze and drink in your room. The rating is for the lake/lounge area, not the service/drinks.
