All of the restaurants mentioned so far offer walk-up, counter service. There is dining inside at Seaport Pizza. The others have inside and patio seating.
Special Tip: SeaWorld at one time was owned Anheuser Busch Company; yes, Budweiser used to own SeaWorld. Knowing this SeaWorld has the best food amongst all the theme parks in Orlando. You will want to make sure you have a full belly on the days you visit.
A slightly finer dining experience that still accommodates the whole family is Voyager's Smokehouse. This is a traditional BBQ style restaurant, complete with red and white checked picnic tablecloths. The menu offers ribs, chicken, corn on the cob and an assortment of kids' meals. The Shamu lunch boxes are available at Voyagers as well.
Spice Mill has a more refined look to it, but it is still family friendly and offers seating outside as well as inside. Burgers are their specialty, though salads are also available. This is yet another place where kids can get a Shamu lunch box. The Spice Mill is located in the middle of the park. This is a great place to grab dinner as it is really beautiful with the lights from the light tower glowing down.
If you have several people in your group with different cravings, Seafire Inn is the perfect compromise. Hungry for Italian food? Hankering for stir fry? You can get those and much more at Seafire Inn, even a turkey sandwich. There are also plenty of choices for kids, including the Shamu lunch boxes! The portions here are really large, so if you ate a big breakfast at your hotel near SeaWorld Orlando, then you might not be able to finish your whole meal.
The most formal dining option at SeaWorld Orlando is Sharks Underwater Grill. Reservations are a must! But it's worth the wait. After hours of walking around in the sunshine, surrounded by crowds of people, it is so relaxing to enter the cool dark restaurant that feels like the bottom of a shark tank. The sit-down, full-service atmosphere is a welcome respite from the jubilant energy of the rest of the park. It's a real adventure when you eat at Sharks. The floor-to-ceiling plexiglass walls contain massive amounts of water and of course the main attraction- sharks!
Whether you are in search of a quick bite or a full-service experience, you will find it at SeaWorld Orlando. If you are there long enough to enjoy lunch and dinner at the park, try two different options. That way you can really get a "taste" of what SeaWorld has to offer.
