Only go there if the weather is kind of nice.
I went there when it first opened in the winter and it was horrid. The walking space was covered with ice and it was not inviting.
But in the summer, it's actually really great to shop, enjoy yourself and the sales.
My only concern is, I find it weird that the dinning experience is not better then this. If you shop Gucci, Hugo Boss and Max Mara are you going to pair that with a foot long sandwich? There is no really decent coffee place either.
