Fixed price meal, with many delicious courses. The lamb in honey with almonds is a favorite, as is the Bistillah (chicken pie with cinnamon and sugar), and chicken with olives. Needn't be done more than once a year, but must be done at least once in your life. Be hungry when you go. And try to avoid the belly dancing, if possible. Excellent decor.
