Indiana currently DOES NOT allow kids in bars open to the public. There should be some adult venues that aren't invaded by children and bars are now about the only place of refuge.
There exists one wrinkle...children of all ages ARE allowed in private clubs with bars...and even in the bar room area (but not seated at the bar). I've seen many time small children running free throughout the area, unchecked by their parents. Babies also are frequently visitors as well. A bar is not the proper atmosphere for small children, especially babies, because the parents also drink as well.
Personally, I want to imbibe without children in my midst.
Is that too much to ask?
