With thousands of observant Jews in Jerusalem, as well as even more halal Muslims, one of the most important assets a restaurant can have is a kashrut certificate. So important, in fact, that there's a substantial trade in ersatz certificates. Since we were visiting my brother, the rabbi, we looked for these a lot. Fortunately, unlike US clties, you can get a lot of really good food in Jerusalem eating kosher, and it doesn't even have to be expensive.
The major kosher food groups of Jerusalem are baked goods, bagels, yogurt, felafel, pizza, and (as of the 21st century) sushi. Having already covered the first, here's some notes (and pictures) about some of the others.
