Not bad...they did take care of my nails pretty well (I had gone there on a particularly...dirty nail day).
However, I guess they didn't realize that I could understand their language (korean), and started talking about how dirty my nails were while working on them in korean...
I don't think I'd ever go back, but since they didn't do that bad of a job, I may recommend it to others looking for a cheap, simple manicure.
