I have been here probably 3-4 times and it is a fine place for an inexpensive manicure. That is the only service I have had, so I cannot speak to the quality of their pedicures. I have always had shellac done here, as it's $20, which is very inexpensive.
As many others have said already, it is your run of the mill Asian-run salon, there are no frills and the service is... brusque. But they do a decent job. It always very busy after work and on weekends, but I have never had to wait long as they always have a lot of staff working.
In terms of the cleanliness, I don't know what people expect from these kinds of salons. It's not filthy or gross or anything like that, but yes, they definitely use the same files on multiple people. I don't love that, but I am also not going to spend $45+ on a shellac manicure, so I deal with it.
The ladies who have done my nails were careful and meticulous, but also fast, which I prefer since I don't have time to spend 2 hours on a manicure.
At the end of the day, you pay for what you get, so if you are looking for a quick nail treatment, I would say you are fine trying this place out.
If you are looking for a more luxury experience then DO NOT come here, as you will surely be disappointed.
Oh also, I have paid and tipped using a card with no issues recently.
