During my last trip in Vegas, we stopped at the Extra Lounge for some drinks since it was smack dab in the middle of the Planet Hollywood Casino.
Basically, the service here isn't that great, and the drinks were not good at all.. Don't get me wrong, I don't mind paying Vegas prices for drinks, but not for shitty drinks... My friends and I ordered LC's, and usually we like them, but the ones here almost killed us.
The only good thing about this place is that it's in the middle of the casino, so you can stop here for a drink real quick if walking around.
