Plenty of people go to Vegas and never even make it Downtown — and that's a shame, because they're missing out on Commonwealth (among other things). This stylish new cocktail bar features a pre-prohibition era design and a drink menu to match, it's own speakeasy called The Laundry Room, and the best rooftop patio in the neighborhood. And don't worry if it looks crowded — at 6,000 square feet, there's more than enough room for everyone.
