If you want to eat good couscous go to El Yacout. The service is friendly and the place is well decorated. It is always in the most unexpected places (i.e. in this case close to the hospital) you find good restaurants.

"Moroccan family restaurant. Oriental sofas and nice cosy corners. More authentic than the known Mamounia, but not very central. Close to the hospital. If you go there plan a long evening with good friends, as the sofas will give you long comfort sitting."
