The first thing to know about Nan Xiang Express - Boston Chinatown is context: a waterfront or coastal backdrop in Boston, United States, matched with the ambitions of a dumpling restaurant. The draw is the kitchen's clarity, hospitality and consistency; at a comparatively accessible price point, it should be judged as a smart choice when you want something considered without turning the night into a major splurge. It is most compelling for diners seeking a scenic meal where place is part of the appeal, especially if the night calls for something more considered than a safe default.
