I recently received a tattoo from Krystof at Bluenote Tattoo, and I could not be happier with the results!
I wanted to add another tattoo to my body to commemorate my recent marriage. Since the artist who did my first tattoo had left Las Vegas a couple years back, I needed to work with someone new. Luckily for me, I did my homework and found the good folks at Bluenote Tattoo. I can't say enough good things about their shop - very clean, welcoming atmosphere which makes for a very kick-ass place to spend some time (6.5 hours in my case) getting your ink done.
Krystof (and his fellow artists, each of Ink Master fame) do a really quality job. While I have seen reviews here mentioning the price was a bit higher than others, I didn't find that to be the case. That said, whatever your perspective, the quality of the work you will receive will be well worth any extra dollars you may spend... Trust me, you will be seeing the art for a long time, don't be cheap now and regret it later.
I would (and do) recommend this shop to anyone looking for their first/next tattoo. Between the great artistry, welcoming atmosphere, and award winning talent... I can't imagine a better shop in Vegas.
