There is a Bar in either Madison WI or Milwaukee WI? -

This bar is secret and you have to get directions to it... and have a password to get in. Once you get in there are like secret rooms and weird things. Does anyone know what it is called and what city its in... my friends and I are taking a road trip this summer and would like to check it out!

Maybe the Safe House in Milwaukee. http://www.safe-house.com
