I absolutely love Sheer Bliss. I've had a couple of pedicures there now and they are always extremely thorough, very professional and help you relax by providing everything you could need... a massage chair, magazines, MTV if you wish, tea, coffee and biscuits. Highly recommended and such amazing value.
Place was clean and staff were competent, but I had to wait for a really long time to be seen. Post-work seems to be really busy for them, I would recommend going during off-peak times.
