There used to be a Turkish restaurant (now gone) around 85th St on the UWS that I would be able to find stuffed Grape leaves.
But other than that, I'd search and search and search and find that no one has good, freshly made stuffed grape leaves, rather than the stuff in jars. Aside of restaurants what stores have them?
Another thing strangely missing from Manhattan's shores is Armenian string cheese for sale (save for an actual Armenian restaurant perhaps). Where oh where can this product be purchased -- especially on the UWS?
