This department store has many attractions. Of course the shopping..but there are also 8 food outlets including the wonderful Brasserie restaurant under the glass dome. However if you want a really sensational view over Paris rooftops, go to the rooftop café called Deli-Cieux. Open Mondays to Saturdays from 9.30 to 8 (10 on Thursdays) it is in the Home Store on Floor 9. There's an outdoor terrace when weather is good, but even if the weather is bad, you can still walk outside and soak up the glorious views to the Eiffel Tower and beyond.
