It's probably one of the better downtown spas. FS is available if that's what you're looking for.
There's a back entrance to the spa. Also kinda spooky, but at least you're not entering the spa with the hordes of downtowners walking by each minute.
I believe all the attendants are Chinese. There is no shower that I have ever used, not sure if there is one available.
The place gets A LOT of clients, and as such, service can be rushed.
One of my fave attendants are Jennifer. She's the same Jennifer that works at Kawaii Spa on Wellesley. Really cute, speaks in a really high pitch voice, okay massage, FS. She works on Thursdays and Fridays.
I would avoid Cindy. She works a lot of the days. She's got this sluttly smile and a pair of fake manmades, but the service is really below average. Hard massages and always gets a call that she answers during the massage. During FS, she gets tired really quickly and tries to rush the whole thing and doesn't like musltiple positions.
Hope this helped you out. Be sure to let us know about your experiences as well!
