I actually happened upon Jersey City traveling from Hoboken, NJ. When I decided to stay a night in Jersey City, I was completely surprised. The nightlife in this city is unbelievable. I would not consider this a family oriented place but if you are single and looking for a good night out on the town then I recommend Jersey City, NJ.
My favorite nightclub there was definitely Sandbar. I honestly cannot wait to for the chance to go back. Another positive to Jersey City is that it is so close to New York City if you really want to go all out. Jersey City is the perfect place for young adults to get out and meet new people.
Aside from nightclubs, there are a few good attractions in Jersey City. Two that come to mind are the Liberty Science Center and the Liberty State Park - located only 2000 feet from the Statue Of liberty itself! If you're looking for a restaurant in Jersey City try Presto's Restaurant on Warren St. It serves up some of the best Italian food in Jersey City.
