I did a birthday party for one of my friends at Demolition Ball & Adrenline Zone in St. Charles. I had a company Christmas party there too. Its a great venue, especially for adults because they have a full bar in there too!! Their website is www.db-az.com. Its off 94, kind of across from St. Charles 18 cinema. You might want to call early to reserve space because they book up quick. From what I understand lots of the big companies (Boeing, Monsanto, etc) are having their employee appreciation parties there so they book up quick. Its a good time and definately something different! Good luck!
