Malawach, Jachnoon in Brooklyn
Hummus Point (1010 Ave. L near CIA; 718-252-2297) serves several takes on melawach, as they spell it. According to my printed menu, jachnun is available on Sunday only, but a phone call couldn't hurt.
Ima's Jachnun doesn't seem to be very active...
...but it's fascinating nonetheless to discover what Facebook-based businesses are out there.
