As others have said, the Beast is available for photos after you eat, but only during dinner. There are no characters at lunch. There is a figurine of Belle in the Rose Library that you can see during lunch (the gallery is closed at dinner and you cannot go look inside). The West Wing is themed from the movie. The main ballroom kind of looks like the one in the movie, but nothing about it really "screamed" Beauty and the Beast to me.
If you want to see Belle while eating, your best bet is Akershus (at Epcot). She's typically the photo package princess over there. She used to be at CRT, but that stopped once ETWB opened in New Fantasyland.
