I was weary of going here because of other reviews, but I'm honestly not sure why people reviewed this place so badly. The lady who helped me did a fantastic job. She was polite, quick and allowed me to focus on work I was doing on my phone. She made sure she understood what I wanted and did a really great job.
The salon was clean, there are lots of chairs available and they are fast.
But if you're worried about it being busy, come early in the morning or make an appointment. They will take care of you well.
