Once upon a time Denver closed up at 5 p.m. with the exception of a few pockets where restaurants and clubs maintained a loyal clientele. Today, that's hard to believe. Denver is a vibrant city of color, characters, sophistication and extensive nightlife options down every street and in every neighborhood. There are lounges, dance clubs, breweries, wineries, speakeasies and a host of other gathering spots that come alive when the sun goes down. The Larimer Square area satisfies the sophisticated cocktail crowd with such options as Corridor 44, Denver's only Champagne bar, and Green Russell, one of the city's hip speakeasies. In LoDo, near the ballpark, night owls can choose between two insanely different scenes: the old-time jazz and blues of El Chapultepec or the uber current ViewHouse, where Millennials gather to enjoy cocktails, play volleyball and bocce or gab with friends in field-side cabanas. In Denver's north quadrant, the country-western crowd still packs the Grizzly Rose to line dance, listen to music and challenge the mechanical bull. And in the RiNo Arts District, Infinite Monkey Theorem puts its own sassy spin on the urban winery. There's even a brewery taproom that caters to heavy metal fans. In short, Denver has it going on across ages, genres and tastes. If it's happening, it's happening here.
