Sorry, I have no ideas on specific places to eat but just wanted to share this:
From what I remember last year at Sea World, it was way overpriced for food. (at least at all the "counter" places) I know everywhere is overpriced for food in the Disney area, but it was definatly more extreme at SeaWorld. I am not a cheap person, but SeaWorld really stuck out to me for being such a rip-off. Also, the kids meal options were non-existent. They had ONE kids meal at each place. It depended on the place for what the meal was. One place was PB&J, another place chicken nuggets, - never more than one choice (at least the counter places we visited....). This really irked me. We walked place to place to find something my son wanted. It would have been nice if they had a couple more kids choices at places. It took about an hour just to find a place for lunch. For example: they wanted $6-$7 (something like that...) for a Smuckers Uncrustable PB&J..... I refused to buy it. What a rip off - I can buy a box of 4 for $2. I know there would be a mark-up on it, but I thought that was insane. I will end up bringing lunch (at least for my son) to SeaWorld for our upcoming trip.
Also, SeaWorld is kind of lacking in the service department. There is a huge difference in the personalities of employees at SeaWorld and Disney.
Not to say we didn't enjoy SeaWorld, we really did. The only things that irked me about the place was the price of food and the employees.
