Besides being a place where you get excellent, and free, wifi - this is a Apple store as you expect…read moreApple's own stores to be from other places (even resembles the fifth avenue store in New York due to its glass walls).
Very knowledge staff, as to be expected, everything Apple and lots of accessories. Accessories may usually be found for better prices online, but for Apple products it is a convenient way to buy (unless you need some very exotic, non-standard configuration of your MacBook).
Also, probably best retail store place in Aix next to the big fountain.
Protip for visitors: the free wifi is available 24/7, even when the store is closed. Excellent to check email on the way back from the bus terminal or train station if you do not have wifi where you are staying.
