In reply to Roberttaylor:
You'll have a choice. La Maison Touareg is on Avenue Mohammed - the way you walk from town to Hotel Les Amandiers - and is run by a lovely man called Sa'id. Maison Troc is on Main road South towards Napoleon's Hat. As with Sa'id above, Lahcen or one of them, cruising on their mopeds, will find you moments after you arrive in town.
