I'm looking forward to pampering myself for my birthday and i'm looking for a spa either in Tysons Corner or Alexandria, something that's highly recommended. I turned to google to look at reviews but I always get better answers on the boards.  
   
 Ladies and gentlemen if you have any recommendations I'm open

It's not your traditional day spa, but a Korean-style bath house, and it's an AMAZING experience. Check out the Yelp reviews (link below), it's not for everyone but damn, it's for me. A day of being soaked, steamed, cooled, massaged, and scrubbed, in a beyond relaxed atmosphere (go on a weekday!)...well, I come out feeling radiant and limp as a noodle (in the best way possible.) And it's a fraction of the cost of a comparable suite of services at a traditional Western day spa.

I really should go visit. :/

Yes people LOVE it there. It's a no frills place but it certainly is relaxing. I think it's 24 hours? I could be wrong on that but go!!!

I especially liked the amethyst room, the clay ball room, and the ice room. Very relaxing and different. And the Korean food was great! P.S. the jets in the bade pool are kind of intense - too much for me. But the massage and scrub - OMG! My skin felt amazing.
