I love dine with Shamu. I have done them all. Its the same exact bufffet, same food for backstage at believe, shamu rocks and Dine with Shamu. With Dine with Shamu there is a little interaction with the trainers. The food at the buffet is actually pretty good. I loved the turkey, a little salty , but good, the seafood gumbo awesome, fresh mashed potatoes. Cookies, carrot cake for dessert. some fresh fruit.
I did the luau too. The luau was nice, the food wasnt my cup of tea. IT was ok, everyone liked it , I thought it was ok. The rice was good, the mahi mahi had a nice flavor.
as for the park food, yuck! THey have smoked pizza, and the burgers were the worst I ever had, no I take that back the worst were in Islands of Adventure, Suess Cafe, awful, just awful, even the fries, yuck.
