What are you looking for exactly? If you could post back with a bit more clarity on what it is you want.
If you were to look for the popular dance clubs, then the SOCO clubs would be your best bet.
That would include Church, Vinyl, 2 AM, Milk Bar and Shelter.

Then there are lots of trendy bars throughout lodo and Denver.
Are you more into Country thing, then there is Country Lounge next to Coors field and The Grizzly Rose.
Are you into coffee houses? Have you been to Paris on the Platte?
Some other clubs are Bash, Rise, Crave, and the one at Champa and 22nd (blanking on its name at the moment)
Hope that helps, or gives you some direction in what you are looking for.
