I live in Raanana just a block away from this restaurant.
This restaurant is a unique one keeping it's interface simple (you have to stand in line to order - Like the famous sup Nazi).
The Humus is served in a unique flavor of Yemen kitchen.
There are many famous people visiting, so you maybe lucky to see one. If...
Huge portions so if you are not use to eat hummus, start if one hummus for 2-3 people. They also have a great falafel and if you want some, tell them even before it's your turn (they ask to do so).
The most famous dish is the Hummahuka, which is hummus and Shakshuka.
This Humus is really very good and worth the effort of driving especially for eating there. Just pay attention that it is a small place, so in rainy days its a little bit of a problem to find a place to sit in (in good days with nice weather they have tables at the street to sit on).
