I have used the services 3 times in total at this shop. Both the top and the bottom ranked people have experienced it, but Yu Yu is the only one who has had the best experience. Both the attitude and the appearance are perfect. Even though I am a foreigner, I don't feel embarrassed when I am served. Besides, she is fun, and she doesn't discriminate against customers. Good luck. I am sure that you will move up in the ranking.
