Milwaukee is filled with events and things to do. Sometimes you just have to dig a little to find them. Last year I was introduced to the comedy scene and there's stand up and sketch shows happening all the time. Prices range from $0-$10. Here's a list of the regular open-mic shows that are free to go to and anyone can sign up.
Tuesday-9pm-Frank's Power Plant (Must be 21)
Wednesday-8pm-Karma Bar and Grill
Thursday-9pm every other week-Art Bar (Must be 21)
There's a great showcase at Karma Bar and Grill every other Friday at 9pm. Tickets are $5 in advance and $10 at the door. There's 2 hours of comedians performing, a combination of local and touring.
I'll be posting more info, just shoot me a message if you have any questions
