Found by chance: a very nice surprise. Would definately recommend it to friends. Having travelled several times in Morocco, I suppose I can tell you the food is good, and very similar the one I found there.
The place is very small, so good for couples of 4 friends max. tiny tables. Good athmosphere, low light, colorfull. The choice is not wide, but the main "classics" are there (Tajines of chicken and olives+lemon, lamb with prunes, cous cous, and so on). Pity I have not seen the Pastilla, a sort of sweet/sour chicken or pigeon pie, rare to find but excellent.
Young spanish girls serving (when I was there, 2009-06), kind but not so aware of the courses, so I suppose don't expect great suggestions.
Worth a try in London.
cheers,
