Zenobia in front of the hotel, across the road, half hidden is a family business run by two friendly brothers who have a short lunch and dinner for groups typical mensaf to order (and no tourists). But if you're tired of the ruins and suffocated by heat, have a small swimming pool where under the palms of your oasis. Tea and dates at will. Very simple, but cozy.
