I had long heard that Abu Shukri has "the best hummus in the Old City." Now, just posing that question risks setting off a war worthy of CNN. But I saw it and stopped in.
It was good. But not great, and not up to the reputation. Of more concern, the service was lacksadaisical and indifferent, even unfriendly. Perhaps it is less open to Westerners, Israelis, or non-Palestinians? I don't know. But I was underwhelmed.
Much better? The nearby Lina Restaurant at 42 Christian Quarter Road, near the intersection with Via Dolorossa. Also Palestinian-owned (lest my above comment be seen as political or biased). And they actually smile at you. Great food, FANTASTIC hummus, and friendly service.
