C-Bar is pretty awesome. Every 2 hours the specials change 24/7, so you can get your drink on and still have some money in your pocket. It's a good place to pre-game before going to a club or just to hang out and drink.
The bartenders are pretty fun, too. I sat down here planning to have one drink before bed one night and ended up staying up way too late because it was a good time... and this is why I feel more at home here than on the south end of the strip. There's no pretense. Just get your drink on. No food is served.
