Just back from the most amazing tour ever - organized by Wild China - with Fuchsia Dunlop picking the restaurants and ordering for ten of us. WOW. I just loved it. I can list some of the restaurants, but really, what you order really matters. I thought the food was just so great - such variety, such fresh food and the food is allowed to shine.
There is another tour happening Oct 2013, if you can afford it, then do not miss it. This was my first time in China, and I can't wait to go back.
Some restaurants -
Qing Yun Lou
Hai wan ju
(also not on the tour but we liked Black Sesame Kitchen and Middle 8th)
Lao Sun Jia
Shun Xing at Century City (one of my favorites)
Yubo (also fantastic)
Dragonwell Manor in Hongzhuo (absolutely stunning amazing great OMG fantastic)
