Located inside of Bellagio so of course this is not a jeans and t-shirt place. It is classy and small. They do need to do more things to bring more of a crowd in, besides their usual herding of the women with free drinks at night, hoping to draw the men in.
Usually, when you do go and have a drink there or two, they will give you a free entrance bracelet to the nightclub The Bank.
All in all, it is a great cozy place to go to, when you want to meet your friends for a drink and chat, before you head out to a loud, noisy bar/club and won't be able to hear what anyone has to say.
