I'm not sure what the bad reviews are about but Diamond Nail Spa has been excellent at sorting my nails out. I've had a gel manicure at 5 different salons around the area and these are by far the best I have had (and at the best price!).
The colour on previous manicures chipped after a few days but these lasted over 3 weeks! 100% recommend and will definitely keep going back here in the future.
AVOID THIS PLACE!!! I hated every second. Made me wait 30 mins after my booking and refused to do the nail art that I had prepaid for. This is an AWFUL SALON do not go. The lady doing my nails also shouted at me and did a really poor job of my nails.
A good experience, went during the afternoon at around 2pm and it was very quiet. Loved the nail colour options, however the one I chose first wasn't available.
