This place is specifically designed for Saudis, so if you want the complete experience then you should go to it. The walls are covered with Saudi proverbs. They also have interesting objects that you can see and ask about.
And for the most important thing, the food. It is good and comes in descent proportions. One thing to note that they make the food in batches so your order could take some time until it is ready.
Finally, they don't have a fixed menu. Call ahead to see what do they have and when are they making it.
