I'm betting Bill's isn't long for this world - considering it's prime location and rapidly advancing age. But I kinda dig a little bit of history, smack dab in the middle of the strip.
I found Dirty Dancing slot machines here ... so that in and of itself was a selling point.
Everything's cheap at this place - another selling point. Definitely a departure from the rest of the strip, but worth a visit. Oh - they also have one of those last minute ticket outlets on site. Got a great deal there.
