The concept of putting a bar inside an enormous chandelier is something that only Vegas could pull off. And to be fair, they did a great job of it. It's a 3-story bar that gives you exactly what you'd expect: really good, overpriced drinks served by absurdly hot bartenders and waitresses. I've been here a few times simply because people I've been with had to have a cosmopolitan in the chandelier bar in the Cosmopolitan. ($13 each, btw) They seemed happy with them. I've enjoyed a couple of their wine offerings in the past, and I'm sure the next time I'm with some Vegas noob who just has to have a cosmo there, I'll try another.
This place is also awesome for people watching, because let's face it, chicks dress to impress here.
The only knock on the place is that some of the couches are starting to look a little worn, which detracts from the whole atmosphere of the place.
