My wife and I have a trip coming up with two other couples. We are all in our early 40s. I'd like to create a list of nice casino bars and lounges. Nothing too "clubby". Just a nice place to sit down and have a good drink. A view would be ok too. I've been to a few in the Cosmopolitan. I thought I heard of some in Mandarin Oriental and Vdara. We aren't really worried about the price but if there are drink specials that would be fine too.
