I was very skeptical of trying out Oxygen Bar. But what a great experience. You do not just get a pure concentrated fresh air but you get a head and a back massage with it , as well as an application of essential oils during both the breathing and massage.
The staff at the Oxygen bar is very friendly and knowledgeable that made the experience even more pleasing. You get out of there feeling a new level of energy. Great if you are jet lagged or just tired after a long day in Vegas.
