WCC is a lot of fun. The staff there really hams it up and gets you involved in the meal. For ex., when you ask for ketchup, they start yelling, "Ketchup run " and whoever has the ketchup on their table has to deliver to the table in need. It's cheeky but fun.
I wouldn't describe Boma as fun. My family thoroughly enjoys it but we love the atmosphere of the AKL and we enjoy the different foods you can try. They have the basic chicken tenders and fries for kids (and adults) who aren't so adventurous.
Hope this helps!
