Need Trenton area Rec’s
Here's a very recent thread: http://www.chowhound.com/topics/378318
You could go to Princeton and have steamed buns (aka soup dumplings) at Shanghai Park. While I've never been to the Princeton location, we have been to the original in Highland Park, and the buns are excellent.
I've also heard good things about Passage to India, in Lawrenceville.
