Where are the Open Mic Nights in Sloop?

Hi Sloopin,

Are there any open mics you know of in the South Loop?

Thanks,

SP

We're familiar with a sweet open mic at Villain's Bar and Grill (649 S. Clark) on the last Wednesday of every month, but besides that we're not sure. Anyone have any other suggestions?
