i don't know about illinois, but in ohio ever since they made that law, there has been no smoking in public buildings and i don't think it will ever change, at least not any time soon. but i personally like it, i don't smoke and i remember going to restaurants before and even though we weren't in the smoking section, i could smell it and breathe it and i had minor allergies so sometimes that would set them off. so i like going to restaurants and not having to breathe in other people's smoke.
