To echo other reviews: Fast, Cheap, and Simple.
Situated in one of the smaller food courts in the PATH system, this place is a real find.
During the lunch hour, on your way to or from The Bay through the underground, it's actually easy to spot this place because there is consistently a long line-up. One sign as to whether or not a place as good is if the ethnicity of the patrons match the food that is being served. Looking at the lineup, you'll notice that it's at least 90% Asian (which may include myself).
I actually aim to be there just before noon but if you are stuck in the lineup, they efficiently have the line move along fast. So the point of getting there early is mainly so that you can get a seat in the food court.
I always order the wonton noodles and basically you just point to the kind of noodles you want, ask for scoops of spicy broth if you want and then choose between pork or shrimp wontons. They also have rice dishes with BBQ pork, and chicken and sides of fried dumplings.
The prices have gone up slowly over the years but you can get away with a good meal for under $6 unless you buy a drink.
