OKW is also close to lots of "offsite" eateries. The Crossings area is no more than five minutes by car (just beyond Downtown Disney) and has Pizzeria Uno, McDonalds, Perkins, Olive Garden and others. Local pizza places, like Papa John's and Pizza Hut, will also delier to OKW -- I am sure of this because I accosted the Pizza Hut man in the parking lot last July!
Downtown Disney also has lots of places to eat. You can take the ferry there, take a bus, or even walk. And if you want to stay put, Olivia's really does seem to have something for everyone. We ate there a lot last visit, and everyone from Grandpa to the kids to my fussy husband was happy. The servers are so nice and the atmosphere is fun, and the menu ranges from chicken and fish to burgers, sandwiches and steaks.
