HAROLD'S DELI Edison, NJ Cakes Display Rig. Harold's will serve you a delicious, diner/deli-esque TUB of Matzoh Ball Soup with noodles, carrots, the whole deal. And a pastrami sandwich with pounds of meat on it. A pickle bar, and all that deli/diner jazz. The cakes are for looking at, i do believe. A great stop near Newark Airport- convenient for the traveling musician (it's about 15 minutes further south off the Jersey Turnpike exit whatever).
