I stayed at the Kempinski Shenzhen several times during my business trips to China. The staff was always very friendly and helpful. And it's simply a great deal! Everything's brand new and shiny - and prices are lower than most other western hotels in Shenzhen.
The food at the buffet restaurant, bar and also room service is amazing! Try the desserts at the buffet restaurant, they're just heavenly!! The GM is a very friendly Swiss guy and the head chef is from Germany.
