If you want to get a cheap mani/pedi, this is a great place to do it. However, if you're looking for anything beyond that, I wouldn't go here. The main reason is that the girls don't speak English at all. Okay, they know the basics, but that's about it. You can't communicate with them, so if something is going wrong, it's going to be anybody's guess as to whether they understand your screams or not.
It's hard to screw up a basic manicure and pedicure, but I probably wouldn't even get gels or acrylic nails here. It's just too scary knowing you wouldn't be able to tell them exactly what you want, and guessing never turns out well!
