I’ve had manicures for a decade and been to a lot of salons around sw London. If you want a simple mani and you don’t care about details, I would go to Posh me (cheaper, better service without sacrificing quality), if you however want good detail - eg don’t want your nail beds drilled off (after getting gel here my nails bend under pressure which wasn’t happening before), care about how even your nail ends are (had to constantly correct) this is not the place you want to go.
