We love the food at SW. I always tell people we bring with us that I eat my way through the park. LOL
Our favorites are the BBQ platters from Smokey Creek. My husband and I usually share a 2 meat platter/fries/cole slaw and cheese cake for lunch. Our sons generally eat their way through a 3 meat platter. It is good enough fare that we eat there almost every time we go to the park. It is a break to just sit outdoors and catch up with each other.
For our dinner meal there if we spend the whole day we head to Voyagers for the Pasta which I love. It is air conditioned so makes a great place to eat when staying for SW at Night. Pizza there is really pretty good, too. it doesn't serve hamburgers etc. and the menu is sort of limited to pasta, pizza, BBQ ribs, kids meals are macaroni and things like that. The pizza is a large slice and served with french fries. 2 smaller kids could easily share the meal.
Snacks: Gotta have the waffle cone of soft vanilla topped with lots of strawberries! Stuff from the bakery up front is very good, too.
You can get hot dogs at Shamu stadium and Captain Pete's over by the dolphin feeding area. I see people bringing food to eat while they wait for the shows in the stadiums, but I would hate doing that. Sharing and planing is so much easier at a table and adds to the fun.
