When the sign is seen from a distance, it looks like it says something else.
What it says is LanaFuchs.com - and what it is is a fashion shop.
It is located on Las Vegas Boulevard, two or three blocks north of The Stratosphere Hotel.
At the top left of the photo you can see the edge of the Stratosphere tower, so that gives you an idea of where Lana Fuchs fashion shop is located.
I do not know what the hours of the shop are, and would suggest calling ahead if you plan to visit. The area is slightly creepy depending on the time of day, so bring your boyfriend, or me.
