My fiance and I love both Ohana and Whispering Canyon Cafe, so that's an option. If you want to stay around the monorail loop, there's Kona Cafe or 1900 Park Fare. Or skip over to Epcot World Showcase to any of their delicious restaurants.
Ohana and Kona are our two favorites. The food at Kona is better than Ohana but Ohana has better atmosphere. So if Ohana is out then Kona would be my choice!
There is no entertainment per say... but we have been there many times with young kids. Last trip the kids were 3 and 1. It is a louder restaurant since it is open air so noise shouldn't be an issue.
