There's a lot to do and see in Vegas, but Harrah's Piano Bar remains my favorite place to visit when I'm hitting Sin City.
I came here for a friend's 21st on a whim and we had an absolute blast. The energy/atmosphere in the joint is absolutely palpable-I don't recall a single person just sitting quietly in their seat, sipping on their drink. Everyone was singing along loudly, even dancing to a few numbers.
The performers are super talented and will play almost anything, just as long as you throw them a tip (standard piano bar set up). They brought my friend up for his birthday and sang "You've Lost That Loving Feeling", which was hilarious.
The feeling of this place is rowdy and fun, but not totally out of control, like the rest of Vegas can definitely tend to be.
If you're looking for a fun night out in Vegas, Harrah's Piano Bar should absolutely be one of your stops.
