I've been wanting to check this place out ever since I first heard about it. A store all about aliens? And it had a giant extraterrestrial outside? Sign me up!
It's a smaller store, but filled with everything alien-related you could possibly imagine and then some. There are lots of really interesting books, some of which are a bit retro and fun to flip through. If there was ever a DVD that had an alien in it, you can bet it's at The Flying Saucer. They also have DVDs of The Twilight Zone and X-Files, Star Wars toys, as well as alien-themed key chains, t-shirts, guitars, and marionettes.
Basically, it's your one-stop alien shop.
Lots of fun to visit when you are in Boulder City.
