:sad: Yes, it is illegal to carry into a place that is posed with the dreaded no guns sign. The good thing is that they seem to be slowly disappearing over time. If I you read the actual law, dry and boring though it be, you will gain a better understanding of what kind of penalty they can levy against you. The owners can file criminal trespass charges. Below is from the law book on the OSBI site, I didn't copy the no guns in bars part as that should be common sense, guns and alcohol and or drugs don't mix... ever!
