The salon was great, very close to the way American nail salons are run, which are much better than the usual salons here in the UK. My only complaint was that I had to wait 15 minutes before a technician was free, even though I had booked my appointment quite far in advance for a specific time.
I had a manicure and pedicure at the Nail Bar, and overall thought it fairly good value for money. The staff are lovely and very friendly, and are also very efficient whilst not making you feel rushed. My pedicure was absolutely brilliant - couldn't fault it at all and it lasted for ages! My manicure unfortunately was not done so well (although it was done by a different member of staff), and had chipped by the next day. Will definitely go back for a pedicure, but probably not another manicure.
