This is Al Sabaa Garden, situated way out on the edge of the DQ and ingeniously fit into a narrow but irregular piece of land overlooking the wadi. I thought it was charming and very nicely done, and I would bet that not a single person I know here even is aware of its existence. It was terraced and full of what I think was aloe, and just a very pleasant place to visit.
