I accidentally saw this big building in the Shanghai International Fashion Center. Next to the Huangpu River, I went in and saw that it was the chocolate world. The whole building was an old factory building. The floor was not high, but the area was very large. The chocolate theater needs to buy tickets to enter the door. You can see a Vienna style. Coffee shops can taste chocolate, coffee, cakes and chocolate supermarkets. There are many varieties and you can also try different flavors of chocolate sauce.
