From your pictures of the NY Tourbillon Boutique, this Boutique has a much more "old-school" feel to it with the inclusion of the art pieces as well as the Tourbillon branded wallpaper. I don't recall the South Coast Plaza Boutique to have any of this Tourbillon wallpaper. If South Coast Plaza has this same wallpaper, it is definitely very discreet and not noticeable at all.
Love your pics of the Glashutte Tourbillon Regulator. The engraving on the movement looks absolutely beautiful!
Cheers,
