I love my nail technician May. She does my gel fill ins and they last a good two weeks and generally go sooner when I am bored with the color. She has great skill when it comes to keeping acrylic nails natural. I always get compliments from people on how great my "natural nails" look and they are shocked when I tell them they are fake.
A bit pricey but you get what you pay for.
Tip: pre game with the girls here before night out with free wine with your service.
