Located just south of the uptown Yonge and Eglinton area, this bar-spa offers clients a hit of pure oxygen to keep lungs feeling healthy. You can either get "juiced" at the bar or book a private room, where you can relax on a lounge chair and gaze at an aquarium. An onsite aesthetician can also provide skin treatments or a spa bath, a 20-minute treatment designed to expel toxins and burn calories. Oxygen is half price every Wednesday, and on Sundays, you get free juice with every oxygen treatment.
