Check out my website, www.kidwinks.com. We list over 100 birthday party places in the Chicagoland area in the Services section. Here's the link to the exact url: http://www.kidwinks.com/ForKids/KidsParty/.
If you become a member of kidwinks, which is free, you can sort these 100+ results in order of distance from your house.
Kidwinks.com is a resource for parents in the Chicago area looking for kid-friendly events, activities, restaurants, shops and services (like birthday party places!). In the restaurants section, you'll find our Kids Eat Free Calendar, where you can click on a day and get a list of restaurants offering kids' dining deals (like "kids eat free") for that day. Check it out!
Hope this helps,
J.
