Shanghai Park in Princeton is your best bet. Way-above-average authentic food in a strip mall on Harrison Street. A bit pricey (like the rest of Princeton). For what it's worth, there always seems to be a large number of Asians dining here when we go. Service is a bit lacking, but food makes up for it. If you're looking for the best in the area, this is pretty much it. Below is a link to reviews (that seem to buttress my case) and directions/map. Make sure you read the reviews, as some even tell you what to order. Enjoy!
