I am one of the last people in the world to be able to vouch for the authenticity of a Chinese restaurant so I am throwing it out there. Has anyone been to Chef Zhu in Del Mar? They took over the old Double Happiness space, which was fairly mediocre Chinese food, at least to my palate. Friends of my SO went there over the weekend, and they expected DH, no more. They stayed, and they were more than pleasantly surprised about the food. I checked out their website and it seems like a step up in Chinese options in the north county coastal region. There are definitely some dishes that you really wont find at Chin's, which for better or worse was probably the best up in the Encinitas, SB or Del Mar areas.
