The restaurant is named Miss Saigon, and it is on Newark Avenue, a few blocks West of the Grove Street station on the PATH. (I don't remember the cross-street; I'm not very familiar with Jersey City). We had the best pho I've ever tried, a soupy paradise of beef fat and vegetables; a delicious squid curry; and that Vietnamese burrito thing where you wrap up dumplings and vegetables in rice-paper panckes.
Jersey City looked intriguing to me; Queens-esque in terms of ethnic diversity and low-profile eateries. Is there any other place like this that is recommendable (and accessible by the PATH)?
