The store was founded in 1900 and furnished in the 1920s with an eye-catching "Art Déco"-style. Possibly cooler still is that it's constructed from glas and iron, but definitely worth mentioning is the café in the top floor. From there you have a wonderful view of the Eiffeltower and the Île de la Cité. Actually, you can get a view of the entire city when you take the spiral staircase up one floor, to reveal a most impressive panorama.
