It's a haul across town on the southeastern edge of the city, but those who make the trek to Ensemble Artisanal will have the rare treat of seeing a cooperative of artisans working on everything from leather to copper to pottery and wood. The Ensemble is also useful if you want to comparison shop: you can get a sense of how the fixed prices here line up with the prices you find in the medina. The ironsmith's lanterns here are of a quality you won't easily find in the medina.
