Bingo! Those ads always ran late at night too. I had no walking money then so I never made it to Dennisons.
Someone earlier was asking about the Egg Skillet in Nutley and I can't say I remember that, but there was a great place in Bloomfield right near the Parkwy for eggs.
If it is the one I think it is, it is still there --- almost under the Parkway? !Small!, but packs a wallop with those eggs fried in a pound of butter on an iron skillet. I can see the name --- but I can't think of it for the life of me!!!! I've only eaten there a couple of times, but my husband considers it the diner of diners!
