Why not rating them honestly but add something like "However, there's no kids menu and it's really not a kid friendly restaurant." The business owner may add a kids menu thinking he is responding to a legit desire of his patrons in an effort to bring them back. How old are you, or do you always fail to think things through?
Wait so then they are actually going to make a kid friendly menu if you do that and people will start bringing their kids to the resturants you frequent. Wtf?
maybe don't give a one star rating though, just include in your review that there's no kids menu or kid friendly options
