After reading the reviews, I went here with 3 girlfriends a few weeks ago when I was visiting Vegas -- we just went to quickly have polish put on our fingers and toes.
The cabbie had trouble finding the place, so make sure you indicate that it's down past the Stratosphere.
Anyway -- it was MEH. There were only two girls working on a Saturday morning and one girl had a bad attitude and was AWFUL. She got polish all over two friends' toes and didn't even bother to clean it off! They could have done a better job themselves.
The girl who did my finger/toenails was sweet and she did a good job, but I would be afraid to try any other services at this place. To say it was clean is definitely a stretch. It was pretty dingy. BUT, the prices were cheap. Needless to say, you get what you pay for here.
If you're staying on the strip, it's far away and not worth the drive / cab fare. The cabbie who took us back to the Strip asked us what we were doing in such a bad part of town. Just sayin.
