What's the best dive bar in Las Vegas? There is no question to me, hands down, anytime someone came to visit me in Vegas, I always took them to a little place called Don't Tell Mama.
Now, some people might refer to this as the piano bar, but basically, the theme, the concept of the bar is that all of the bartenders are singers. They'll be singing half the time while they're making you a drink.
There's a piano inside of the bar where there's an amazingly talented piano player playing these amazing tunes. And then also, it's like a piano bar karaoke. So say, for example, like Mondays, the Cirque shows are off. All these incredibly talented singers come and do these karaoke performances with this piano that would just blow your mind.
And then also, if you want to get up and you've had maybe a few shots, try your turn at being the star of the karaoke; you are welcome to do that. Good luck.
