The Crooked Spoon is just a restaurant (you may be able to use it as a bar if you're sitting outside?), but I have seen a few different types of entertainment over all the times I've dined there, wether that is a singer, or a walk around character (such as the Enchanted Village Mayor...), I've seen balloon shape making, and I think in the summer there may be out door entertainment, although I'm not sure what this consists of. To my knowledge, there isn't any set schedule of entertainment for the Enchanted Village, however it might be worth checking out the Alton Towers Hotel for that kind of thing. Link
Having had another look, Alton Towers website says:
You'll be able to enjoy plenty of family-friendly entertainment in the Enchanted Village. You can also make the most of activities taking place in the Alton Towers and Splash Landings Hotels, from children’s shows to live singers.
(All entertainment varies between peak and off peak seasons. Guests cannot access facilities in the CBeebies Land Hotel).
