Great place for raiding the shelves. That is if you are into branded goods. From LV to Chanel, Miu miu and so on, you want it, they have it.
TIP: Don’t rush to the first level boutiques and buy what you want. You might end up being caught in a damn long queue with not-as-patient sales assistants.
Every level have the same boutiques and going further up means lesser queue and people.
All 3 buildings are interlinked and its HUGE! If you are tired, have a hot chocolate at the famous Angelina, thick and yummy. (Not recommended for those who doesn’t wish to spluge on food.)
