Commonwealth brings together music and drinks in a space with chandeliers, lots of brick and a party atmosphere. In addition to an impressive number of beers on tap and by the bottle or can, including Coors, Guiness and Dogfish, the cocktail menu is full of potent creations. The Little Hot Mess combines Bacardi Dragon Berry Rum, fresh lime juice and muddled strawberries, and The Dude Abides pays homage to "The Big Lebowski" with raspberry vodka, coffee liquor and Irish Cream. The rooftop patio gives you a great view of Downtown Las Vegas, plus there's often live entertainment. This isn't a lounge for quiet conversation, but it is a place where you can dance and drink all night long.
