I'm not familiar with any restrictions regarding restaurant capacity as relates to carry, open or otherwise. Arkansas, in my opinion, is still a "carry at your own risk" endeavor. I know what the law says, but that doesn't mean you won't be harassed or even arrested by LEO that either aren't familiar or don't agree with the new law. It varies from city to city and county to county. I know this because I have a prosecutor in the family.
