Generally, you can rely on Selfish for a good gel manicure and always leave happy. My only watch out is who you get as your nail technician. For the most part they are really good, but a couple are clearly less experienced, and leave you with un-neat nails or feeling rushed. I think it’s worth asking who will be doing your nails / requesting someone who has done them well before. It’s not cheap and for the most part it’s worth it, but not if you leave with messy nails!
