My friend and I were looking for an affordable place to get mani/pedis while we were on vacation in Vegas, and we lucked out that Groupon was offering $35 for $75 in services for Vdara salon.
It was--by far--the best deal I've ever gotten with a Groupon. The salon is located in the new Vdara Hotel, just off the Strip. The hotel is elegant and modern, with very simple decor, which was a nice change from the gaudiness of the Strip. The spa itself is very clean and the staff were all very nice and friendly--especially our manicurists. The pedicure was so relaxing, especially since we had spent the previous day hiking at the Grand Canyon. They really took their time to provide the best quality mani/pedi, and they didn't once try to push any of the products on us.
I'd definitely go back to Vdara next time I'm in Vegas.
