Some of you might already know about this, but I wanted to share the ridiculousness for those who don't.
The most pricey cocktail in Las Vegas is at Wynn's XS nightclub.
It's called the Ono.
And it costs a cool $10K.
Includes drinks for two plus custom jewelry for "him" and "her." (Souvenir glassware is also included -- just like those yard-long margaritas, only shorter!)
More details here and here.
Bottoms up, y'all!
