Bill's is definitely one of the more ghetto casinos, but it's still pretty cool.
The main attraction here is "Big Elvis". How big is he, you ask? He's big. Really, really big. But more importantly, this man can put on a SHOW. His "King" impression is so spot-on, I'm betting even the most rabid Elvis fans would be fooled. He does free shows every day at 3, 4:30 and 7 in Bill's tiny, tiny lounge. You should check it out for sure - but get there early. It's a hot spot and hard to find a table.
As far as gambling goes, they have some decent cheap slots - among my faves were the "Alien" movie-themed penny slots. Plus, I got a few free drinks as the floor is small, and the waitresses are plentiful. And I think it was only around $5 or $6 for regular bar drinks (that's super-cheap in Vegas!).
It's also worth noting that this was the ONLY casino on the strip I won anything at. Coincidence? Or the magic of Big E? You decide.
