3 1/2 stars.
I've been to Sugarmoon 3x in the past year, all for brazilian.
First two visits were very good experiences. I can't remember the name of the ladies but they were both professional, friendly and did their best to make the experience pleasant as possible by keeping my mind away from the procedure.
However my last experience with Greta was not a good one. Although Greta was professional, (not as friendly as my previous experiences) her skills were not up to par. I wasn't satisfied with the immediate result. Worse than that, after the appointment my skin was very sensitive and red.
I would go back to Sugarmoon but I am going to be more picky about the staff I see.
