I've been here a handful of times as it is the closest pedicure place in Cen Pho, but like many other reviews have mentioned, unfortunately it seems that often the wait is a lot longer than they quote you for- and you're already sitting in the chair so it seems ridiculous to leave after thirty minutes of doing so.
That being said, they give great massages and know how to do it up when they do get to you. I recently brought in a couple men who hadn't had pedicures in a few years and they were pretty good sports about the gnarliness of their feet.
I'm sure I'll find myself here again, but I know that it isn't going to be a quick experience. Also, not open on Sundays- what nail salon does that?
