This place was recommended to me by the lady who runs the riad I stayed in. I didn't go for a couple of days because I (wrongly) thought it would be "just another recommendation" - I was wrong! Loved it so much I ended up going there about 4 times in total during my stay.
Service was good and attentive (and the same could not be said for numerous other places I ate in Marrakech), food was always very good (think perhaps more relaxed and informal than formal dining) and the places itself has a fantastic, relaxed atmosphere - mostly due to the large plantation in the central courtyard but also to the multiple levels it has. One night there was an old film being shown on an outdoor wall upstairs with sofas aplenty to take it in. WiFi works well.
It's, from what i could fathom, owned/run by the same French people who operate the, equally worth a look, Terrace des Epices and Cafe des Epices.
Really enjoyed going there, as did the people I took there, and would go back again.
