Nobody could sue you for that. (That's not actually true. A person can sue another person for any reason. It is up to the court to decide if the suit has merit)

But at least it isn't a trademark issue, as there presumably aren't any restaurants (or businesses in other competing industries) who you could be confused for -- in your state at least.

As far as I can tell, there is no "copyright" issue.

Disney has sued people for using their images (like painted pictures of Mickey Mouse in a day care center), under some sort of copyright or licensing infringement. I bet they won, but I don't see what their justification could be. I vaguely them claiming that the use of their art by third parties could be seen as an unauthorized endorsement of a business by Disney. That's closer to trademark law than copyright law, but I think Disney won, and trademark law would have told Disney "tough titties".

Let's not forget that Disney thinks they own Cinderella, Snow White, and dozens of other hundreds of years old fairy tales. Their sense of entitlement is unbounded.
