Quick holywood wax - staff are skilled and friendly! May not be the cheapest deal on treatwell, but they service is consistent and reliable and you can book with only a day or two's notice.
The venue itself is great and very cute but there was a lot of confusion when I was there which meant my quick appointment was quite long. I was also almost charged double the price and instead of a waxing that I had booked my eyebrows were threaded. The staff are also very pushy towards buying blocks of appointments. I will probably go back as it may have been a one off experience.
