Zabulon Simintov always removes his kippah, the skullcap worn by Jewish men, before entering his cafe in a dilapidated building that also houses Afghanistan’s last synagogue.

“Let me take off my cap, otherwise people will think something bad about me,” Simintov said cheerfully as he descended grime-caked stairs to the ground-floor cafe.

In his 50s, Simintov is the last known Afghan Jew to remain in the country. He has become something of a celebrity over the years and his rivalry with the next-to-last Jew, who died in 2005, inspired a play.

Mindful of Afghanistan’s extremely conservative Muslim culture, Simintov tries not to advertise his identity to protect the Balkh Bastan or Ancient Balkh kebab cafe he opened four years ago, naming it after a northern Afghan province.
