My wife moved to this salon from a more expensive one where there is "great service" and "ambience". Quality of the cut? Pretty much at par with the more expensive one! Ms Li cuts her hair and the layering looks awesome.
For the price and the quality of the cut, five stars. Well, as for the cleanliness and service, it is not part of their charge so you don't pay for it and so you don't get it. :) Well, from experience they do serve people well - especially those who are polite and respectful to them.
The hairdressers there are very friendly. No reservations. Just walk in and Charleson (or at least this is what his name sounds like) does the queuing and helps decide who goes next. So be early otherwise you'll have to wait for hours during weekends
Bring cash just to be sure.
