I go here regularly - the main thing that irritated me was that I had booked an appointment for 6:30pm and did not get my treatment until 7:10pm whilst others who hadn't booked or had later appointments were served. Not ideal! However the treatment was great as usual so will definitely be returning, just be prepared to wait!
Incredibly convenient for me as it's just around the corner. They're great at accommodating whenever they can- it's always very busy but this works well for me.
Regularly get my nails and wax done at USA Star Nails as they're very efficient- especially the lady who does my wax, it's never enjoyable but she manages to make it at least quick for someone who's a massive whuss!
