Their work is good quality for moderate prices. Niki, the owner, is the best in terms of workmanship.
The store however is generally very messy and the staff are rude and not accommodating. They often quote you one price and charge more because they "quoted wrong" in the first place.
Communication is also very challenging since everyone doesn't speak great English (or Cantonese Chinese), so it would be hard to get your exact ideas accredited if you don't speak Mandarin Chinese.
Appointment times usually run late as well, so expect to start getting your nails done at 7:15 if you booked 6:30. Expect no apology for lateness...they aint about customer service there :S
