I've been to Glow several times for eyebrow waxing. The service is always excellent. They have a quiet waiting area. Their waxing rooms are private and very clean.
I really like that you can make your appointment online. They then send a reminder email the day beforehand so that you don't forget.
They do accept various methods of payment, including credit cards. The only frustration I have is that you can not add a tip when using credit cards, so you must bring cash for this.
