I visited about 2 weeks ago and saw Shawna (If I remember her name correctly, she is about 5'7 or so a bit on the heavier side but not large).  Below average massage, extras were expensive, if I went back I would see someone else.

I've never been, but there are a lot of write ups on "www.gentlemensreview.net".  They apparently only do HJs for about 5 jacksons beyond door fee, and YMMV.  I don't know of other good spas/parlors in the boston/burb area...I usually drive down to Providence to see the korean lovelies when I need a good back rub.
