I have been there twice - once for gel, once for polish only.
The ladies are always really friendly! They offer you a beverage (I had a delicious tea) and I find that they don't try to make small talk which I appreciate. They show a movie, which is good to pass the time.
I wasn't incredibly happy with the gel. The manicurist refused to cut my nails short, and as a result, my nails chipped due to my typing all day long at work.
I am really happy with the polish. I chose a regular OPI colour in off-black, and it looks like gel! Very happy.
4 stars as I wasn't overly happy with the first experience, but no lower because I was happy the second time around.
