Finally, for all of you who have wished that there was a real Deli from your neighborhood in New York, in New Jersey, the answer may be Irving's on Route 10 in Livingston.
I've been there twice and have left happy.
There is no Irving. The owner hired a guy from Katz's in NY, taught everyone how to hand cut pastrami, brisket, and corned beef, modelled it after Katz's even in the decor. You get a ticket at the door, order your sandwich, get a sample as they are cutting - they give you the sample whether you tip or not, get a drink and take a seat.
The pastrami and brisket were spectacular. The corned beef very good, (though I'm partial to pastrami, if I had to choose). Really good rye, (bread didn't fall apart when confronted with moist meat.
Good Yonah Shimmel style knishes.
