San Francisco’s only authentic Eastern European banya experience, Archimedes Banya is where to go to sweat it out in a friendly, clean and contemporary looking day spa environment. Okay, you’ll have to get used to detoxing naked with members of the opposite sex, but as long as you’re not hung up on your body, this is the place to do it. Combining ancient detoxing with heat traditions of Greek laconica, Turkish hammam, German thermen and Russian banya with modern rooms and pools, and a sun-lit deck with stunning views, it makes a great location to recover for jetlag especially. They also have a healthy restaurant and a spa offering a menu of massages, scrubs, wraps and herbal and mineral bathes.
