At work we had a birthday lunch outside with a Sukkah tent. These temporary structures are popular all over Israel as a place for Jews to eat and sleep in them for this festival. Sometimes they are tents and some are shed like buildings, they are decorated with palm trees, plastic or real fruit and Christmas-style decorations, kind of all the fun of camping but just outside your house.
Just off the side of Jaffa Street, there is a huge Sukkah put on by Jerusalem Municipality. There is local artwork being shown inside, and behind was a stage with a big free concert is on, there was some Ethiopian girls singing in their native Amharic language. Of course there wasn’t any English commentary to this show, so I don’t know if this was a charity event.
