I doubt that Tolkien was a grand slam sort of guy.
Oh, look at that: another movie tie-in by a company in a vein attempt to win over the masses. Will it work? Well OBVIOUSLY it does or they wouldn't continue to keep doing it. The Hobbit is coming out soon enough and naturally, it's time to start the marketing. Just as the title suggests, it's Denny's and a Hobbit themed menu ( for a limited time, mind you) because eventually the age of Hobbits will pass and the time of land whales will return.
