Buffalo Wild Wings in Cleveland, TN (Paul Huff Parkway location) has a very hidden sign in the bottom corner of an entrance banning guns in their restaurant. The sign is smokey in color so it's almost invisible on the tinted glass unless you're looking very hard for it. I encourage everyone to send letters, emails, or call to ask them not to post. And in the meantime, go elsewhere for your dining needs.

This does appear on their doors. May not be the legal version, but still gives enough of a hint for you to respond as you care to.
