The signboard tells you all, there's the celebrity restaurants, Expo and Convention Centre, Casino, Hotel, etc.
There are two basements of shopping, I think. A lot of places boarded up so I cant really tell...lol.
There are shops that sold branded goods but there are just as many shops that are affordable to the average shoppers. So if you are around Marina, do pop over here to do some shopping or window shopping. It is a nice place just to shop or have meals/coffee with your friends.
The food court at the basement, very small and not enough seats. I think when completed, there's a bigger food court. It will be silly if there's no bigger food court in this big complex cause not everyone wanted to eat in restaurants.
