Even though thie might not be something really extraordinary in a city where extraordinary is the norm but i still think you shouldnt miss this place if your visiting (like who really lives in Vegas, right? he he).
This place is about a 10 min cabride from "the strip" and is often refered to as "old vegas" where the first old casionos where back in the (ok Flamingo excluded).
You have Binions and Golden Nugget and such old school casino hotels as well as the famous Vegas Vic cowboy who used to wave his hands to the visitors of Las Vegas.
Today you have a roof over Freemont Str wich is also a huge screen where you can see music videos or other fun things depending on what time you are there.
Its lots of people, restaurants and bars as it is on the strip just a bit different.
My inside tip if your in the area and suddenly feel the urge to eat a fantastic steak in an mens cigarr club kind of a setting: Vic & Anthonys inside The Golden Nugget.
Best steak in Vegas with nice ambiance and great servers. Bring your big wallet though because quality come with a price tag.
