Colorful characters from Denver’s past are rumored to have bellied up to the bar at Charlie Brown’s, which has been open since Prohibition ended. A sprawling spot with nightly piano sing-alongs, it lives up to its slogan: “Something for everyone.” Couples, friends, tourists, young professionals, senior citizens, college kids and even celebrities enjoy the stiff drinks, huge food menu, enclosed patio and free drinks for revelers celebrating their birthdays.
