I only stumbled onto NJ hot dog culture a few months ago, and was wondering: Are fried dogs unique to northern NJ, or does the rest of the world know about them and I just never noticed? Also, for Italian (or Newark) dogs, are all Jimmy Buff's created equal? I wasn't too impressed by the Irvington one. It wasn't the grease load as much as the lack of other flavors. Would a trip to one of the others be worthwhile?
