Came in and was immediately quoted $240 for two tattoos for a friend and myself. Monk (the tattoo artist) offered to do them both for $140, which was very reasonable considering the location. He was so friendly and made us feel completely at ease in the tattoo shop. He even extended his normal hours to accommodate our busy Vegas schedule! In the end we couldn't have asked for a better experience and our tattoos came out great! Monk is a great artist and makes the whole experience memorable and fun! The space itself was also very clean and welcoming. It definitely doesn't feel "scary" or "seedy" in any way, shape, or form. I would send anyone to Monk at Atomic City and I'm so glad we had the opportunity to have our tattoos done there.
One tip to keep in mind though is it's a little difficult to find, but when they told us three blocks before the stratosphere we had little problem after that, trust me the search is well worth it!
