Fun or interesting = Raglan Road to me, and we enjoy the food. House of Blues is a possibility too, but we haven't been in so many years that I can't vouch for the food.
Be aware that many of the restaurants in DS take reservations via Open Table as well as Disney's ADR system, and sometimes it's easier to book via OT (more availability). The OT cancellation policy is more flexible, too - there's rarely a penalty, even when cancelling last minute, although the individual restaurants set their own policies in that regard.
