Visiting New York City – real Jewish Rye?

Visiting New York City – real Jewish Rye?

I will be visiting NYC later this month.   Since I make and sell what I call New York Rye, which is a actually a Korn Rye  such as I imagine may have been sold in New York until say the 1960s, I am wondering if the real thing still exists.   I would love to compare what I’m making with the indigenous variety if it is still around.   Anyone know?   Also, I love Ess-a-bagel but wonder if there is actually a less automated and perhaps more authentic bagel shop in the New York area.   Yes, I know, you can’t go home again, but since I have never lived in NYC, that doesn’t really apply.   Thank you!
