Club Evolution opened last year in the building that was once home to Muddy's but looked wrecking-ball-worthy in recent years. Fresh from a floor-to-ceiling overhaul, the place is now a gorgeous, two-story jewel of a club with an intriguing split personality. During the day, the upper level welcomes a wi-fi crowd for coffee; by night, the brick-walled room serves as a comfortable cocktail lounge with great drink specials. (Look out for the rolling chairs, however: After the crowd has a few drinks, the place turns into chair-derby.) Downtairs is a bumpin' dance club where the city's chicest assortment of family, and friends, come to be seen. No wonder there's a line out the door on Fridays and Saturdays: Evolution is the smartest combination of elements we've seen in Denver nightlife.
