Where to eat after the Opry?
There's really not anything remarkable in that area. Probably the best bet is Caney Fork Fish Camp -- a theme restaurant that wants to be a chain, but isn't yet. You could drive a little way and go to Ellendale's -- they close at 10, though, so you'd be cutting it close.
