That's true yea. Ive been to Vegas four times, last time was for my mates stag (long) weekend, four days in a row i had breakfast in a casino. 
  
I found the MGM grand the best, thier is a few nice bars/clubs in the MGM itself.  Thier is a really nice piano bar on the strip, not sure where abouts it is, I will try and find out and let you know.  
  
To be honest though, the place has so much stuf to do, you'll find some place that suits you.
