Yes, part D of 95.4 says that LEO are not allowed to arbitrarily search you for a firearm if you are in a restaurant. Course, if you are OCing they don't really have to search you to find it do they? Then your popped for 95.5 if the place serves alcohol to diners.
This is not to say that people haven't OC'd in restaurants that serve alcohol. I have and so have many others, but ya takes your chances if ya do.
