In Hackensack, White Manna, stunningly beautiful, historic and good food, too.

Northern New Jersey is in the midst of a fried chicken craze–KFC or Korean Fried Chicken. Many of the best kfc the restaurants are located near the terminus of your road trip. Here’s a link to a Times article http://www.nytimes.com/2007/02/07/dining/07fried.html?partner=rssnyt&emc=rss
Plus a good overview at Off The Broiler http://offthebroiler.wordpress.com/2007/06/13/nycnj-dining-the-great-korean-fried-chicken-round-up/
New Jersey loves hot dogs, especially deep-fried ones called rippers. This isn’t my area of expertise so I refer you to a HollyEats section on New Jersey Hot Dogs. http://www.hollyeats.com/JerseyDogs.htm
