This is THE place to get knishes. They are head and shoulders above any knishes I've gotten elsewhere. Especially the kasha ones—I don't think I've ever, in recent decades, found a kasha knish that was at all good. But Yonah Schimmel's kasha knishes are delectable.
The counter holds a selection of types: potato, kasha, vegetable, etc. They also have a few other items: rugeleh, herring...that kind of thing. When you order your knishes, they ask if you want them heated up. There are some tables in the back where you can eat, but I've never sat down. I just buy my knishes and take them away.
I was surprised but happy when I found that the place is open on Saturday (the Sabbath).
You can also buy Yonah Schimmel's knishes online. See
