Try 'mandi' at Marmara Turkish Restaurant in Al Saad. Perhaps you can request the steamed chicken to be replaced with an oven-grilled one, and asked too for a mashed tomato dip. It's as close as the saudi 'kabsa'. When I was in Saudi I have to drive all the way from Dammam to Thokba just for this. And oh, I missed samoosa too. Haven't tasted something as good as the ones sold in Saudi. :)
