it's orange rice and grilled chicken, yes orange and chicken, as you can find tiny slices in the rice. it's named as Bukhari from Bukhara, a town in mid-Asia, so as it's widely known. i guess this dish had travelled with the pilgrims from Bukhara just to become one of the main dishes in western saudia. you can find this in any of these take-away local restaurants. they're quite obvious as you will see big steel machines for grilling chicken in rolls and rows.
they're not my favourite but i remember my grandma used to cook us Bukhari rice and chicken each time we visited even if that meant everyday; yes, it's that popular!
Favorite Dish it usually comes with tomato and spicy sauce, and perhaps basic salad (onion and cucumber).
