In Hangzhou just off Honglong Lu, in between the park and the stadium, there is a tiny little uninteresting door that leads to a fancy restaurant on the second floor. Look around and you'll find it. It's by the bank of Hangzhou.

They serve mainly Chinese food, but also the most high-quality steak I've ever had, covered in a fine cheese. Everything they serve is gourmet, but their shrimp congee is probably the best thing you will eat, in your life. Really expensive though. I have to stop myself from going to Hangzhou, because every time I do I end up blowing 400-500 on a dinner for two.
