Current Ohio law prohibits firearms by law abiding citizens in almost any commercial establishment that serves alcohol for consumption on premises if anyone in the facility is consuming, even if the armed citizen is not. The only current exception for most people is retail stores such as a grocery store doing a wine tasting. In that situation, a person can carry as long as they do not drink any liquor.
HB 203 would extend that exception to restaurants, again provided that the person carrying a firearm for self-defense does not drink.
