I found Imperial Spa by accident 5 years ago. It was one of the best finds ever!
Every time I'm in Vegas, this is a must stop. I love the srub/massage. My entire body gets so smooth and glows. The Spa is awesome. I love spending hours here (sauna, steam room, the waters). They have a great resting area along with a great dressing area. The prices are better than the spas in the resorts.
This is one of those places that you walk in tired and come out feeling like a newborn.
Looking forward to my next visit!
