This place is AMAZING.
I get a massage around once a month because I have scoliosis and my back is always somewhat sore. This was the first massage I've ever gotten where I felt like every knot in my body was thoroughly worked out. Although parts of the massage were somewhat painful, the end results were worth it. The best way to describe is that feeling after you roll your legs out after a workout, but for all your tight muscles!
This is the real deal - they walk on your back, they stretch you out, and you'll emerge a brand new human being. They'll provide loose clothing for you, but I'm sure you can always just wear your own, like other Thai massage places.
