I have tried several well-rated nail salons for SNS around London and none do the job as well as Pure Essentials. I travel from Tooting to Kings X to get mine done here, they’re always perfect and last 4-5 weeks without a chip! Lovely little nail bar, friendly couple and they always offer you a drink. Go here for SNS!!! Trust me. I also never leave reviews unless the service was amazing so there you go lol
