Apparently this restaurant didn't have a sign saying, "No Motor Vehicles Allowed in this Building."

No, the sign should have said "This restaurant is a motor vehicle-free zone"

Most schools and commercial buildings I've seen don't use "gun-free zone" on their signs. They say that guns or weapons are not allowed.

Here is a link showing signs required in each of the states.
