This is a really beautiful place. I have never seen so many different cacti - some of which look incredible lethal! The building itself is superb and the jewellery section of the Berber museum is very inventively done with myriads of tiny lights which make you feel as through you have walked through a mirror into a different world.
Nice café - though the fruit juice is hugely expensive.
The shop is a bit snooty and over priced. Also I would recommend going early in the morning because it gets really busy.
