I'd describe my experience here as *fine*.
I couldn't find it for a while as I wasn't expecting it to be in the basement of an off license and to be honest I found this a bit off putting. I had a fan placed between my legs "to dry the wax faster", which I found odd and awkward. The wax was incredibly hot and the waxing very painful; I normally have a pretty high pain threshold.
The end result was okay, I've had much better and also worse waxes, so if you need a last minute wax and don't mind a scruffy and not 100% clean salon then Riddhi's will do.
The therapist mentioned that they were moving location so perhaps the next will be an improvement.
