Do you like characters? Then maybe.
I am not a big fan of character meals, as you can rarely get a good picture with the characters (the background is always crowded with tables and people) and you have to be lucky that you get a good table which the characters do not overlook. But also not at a place where they leave quickly, and hope that it is not too busy.
It's a fine buffet restaurant, do characters really improve it? For a fan of characters it might.
