What's In Las Vegas?

I don't know what's in las vegas nevada but my best friend in college who is in Chicago now working as a nurse, always go to that place every year. It must be a nice place. So if ever me and my family can go to USA, Las Vegas will be one of the place that we are visiting. But it will not happen soon because we are relocating to Australia temporarily. If the retrogression will uplift. Then maybe me and my family can get our green card and I can practice as a nurse in USA, but depending if we will like it down under. I will decide when the right time comes.
