As soon as you go to the observation deck on the top floor, you can enjoy panoramic views of Paris from the Opera and the Eiffel Tower far away. It's free and just below is a restaurant like a food court, where you can dine with the Paris view at a reasonable price. Best of all, it's a great place to get a tax refund. It was nice to be able to receive tax refund cash on the spot on the 1st floor and have Korean staff, so it was easy and quick to handle all the processes. I think there is another thing like this for busy travelers.
