This swanky little pocket bar is open to everyone, but its spot in the high-limit gaming area on the second floor of the casino (no, you don't have to play) makes it a well-kept secret for drinkers who want some privacy. Mixologists don't usually offer a cocktail menu; instead they simply ask you what you like and craft drinks from there. Perhaps the only downside is the prices, befitting the decadent setting.
