I make the road trip from New York City to Philadelphia about once a quarter taking the New Jersey Turnpike, and I'd love to hear more places that are slightly off the beaten path. I think you can take a parallel route along the US 1 and the 95 if that is more interesting. I'm interested in coffee shops (fancy or otherwise), doughnut shops, or regional specialties. I already know about Harold's New York Deli in Edison, NJ.
Note I'm not looking for anything inside of New York City or Philadelphia, but only what's in between.
