Park West is a popular venue in Chicago. It has been known to host local artists, musicians, comedians, and conventions.
My first time at Park West was for a Warren Miller Ski Show. Many vendors and representatives from all around the United States came to promote themselves. There were ski give-aways, a documentary, and Olympic speakers. This just shows what this place is capable of hosting.
Mostly Park West is known for hosting musicians and with a large bar it is ideal. (Although the beer is of small selection and a bit over priced). Check out their schedule before visiting and see if there is anyone of your interest to see.
