You really can't beat a $20 gel manicure. With that being said, Holly is the best. I can't vouch for anyone else. She spends a lot of time perfecting the cuticles and polishing the nails so they look fab :)
I think their gel polish selections are lacking, specifically OPI. They should really increase their shades, particularly seasonal colors.
Also, I've called ahead for appointments and still end up waiting upwards of 20-30 minutes. They shouldn't take appointments if they can't be timely.
