Dingtaifeng is a Chinese restaurant in Guangzhou, China, and the useful context is what kind of evening it seems built to deliver. Readers should look for regional technique, texture and the rhythm of shared plates, because that is where a restaurant of this type earns its reputation. It is most compelling for diners seeking flavor, texture and a point of view rooted in cuisine rather than decor alone, especially if the night calls for something more considered than a safe default.
