[Looking for cocktail bars in America]

Can anyone tell me of any cocktail bars in America that are chains? I am not looking for one off bars (no matter how great they are) I am lookjing for a company with a chain of 10s or better still 100s of cocktail bars especially if they are kind of party atmosphere bars rather than upscale cocktail bars ....... hope someone can help
