It was in my hotel so it made it convenient. It's a chic lounge outside of the Beattle's Revolution Club. It's not bad since it's a great place to hang out to enjoy a drink, hang out and listen to great music. If you want to go into the club it is $20 before midnight or $10 after. If you stay at the Mirage you can get in for free before Midnight.
It's a decent place to just enjoy great drinks, music and just chill. Try it out, you might be pleasantly surprise.
