As someone mentioned, it's a nice upscale gift shop. However, when I went in today they had a 50% off sale on a couple racks. They also have a sundries area, which is nice and convenient for guests of the hotel.
I came in to pick up some scented sticks, the air fragrance in Crystals. However, there was another scent used in Aria that smelled like Vanilla, so I got that as well. Each stick lasts about two weeks and a container is about $25. You can put them in your air vents and they'll freshen the air.
The good thing is the store is open 24 hours.
