This place is ok. I usually come here for regular pedicure and most of the time their job is neat. It really depends on who's gonna be working on your nails. 4 times out of 5 they do a good job.
I tried manicure once and was disappointed. It started chipping that same evening.
I also tried waxing (half legs) and they were not wearing gloves neither I saw them sanitizing hands! Never again!!
As for sanitary... They do use plastic bags, not linens. But what's worse, when the bag is taken out, they may ask you to put a foot down! Be aware of that and use your brain while being there.
