As far as we can tell, all of these exclusive shops are simply maintaining a presence in the hotels. Fancy advertising really. You never see anyone in there, and usually only one lonely looking salesperson gazing out to the walkways.
The coolest light-up pad for the bill at Michael Mina's restaurant in the Bellagio. Why doesn't everyone have this technology?? In Vegas you just charge it all to your hotel, no matter where you are eating. Nice.
