Thursday: None that I know of
Friday: Kinki at the Cube
I tend to go to all of the cheap nights in town, but go to Jesters/SoBar whenever I feel like it, seeing as it's already pretty damn cheap there, and it's ridiculously busy on their cheap nights. I personally never go to Oceana, really. Whitehouse in town is also pretty groovy, but it brings out my mischievous side, and it's also quite expensive.
