Once upon a time Denver closed up at 5 p.m. with the exception of a few pockets here and there. 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. Uptown is home to Retrograde, just one of the city's speakeasies, while the Highlands is home to another, Williams & Graham. 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 RiNo, nightlife options include urban winery Infinite Monkey Theorem, gallery/speakeasy Millers & Rossi, and Death & Co, the first outpost of New York City's famed cocktail bar. There's even a brewery taproom that caters to heavy metal fans. In short, Denver has it going on across all areas, ages, genres and tastes. If it's happening, it's happening here.
