Request for best kosher take-out in Jerusalem
For wine, start with Machane Yehuda. Try the Basher Resto Bar on Agrippas, and ask the owner Itamar Ben-Zaken for a tasting and a tour of the wine cellar. They open around noon.
Lots of take-out options on Emek Refaim. For a complete Shabbat take-out dinner, Marvad Haksamim is a great option.
Enjoy your trip! Wish I was going too!
