Do you want to eat near the airport or Disneyland? Do you want something like In N Out, cafe, or restaurant? Mexican, American, seafood, sushi, other cuisine? There are a ton of places to have a bite to eat. You might want to just go to your hotel and have a bite at Downtown Disney or Whitewater snacks at the Grand... There are also a bunch of places on Harbor that you can go to, or Gardenwalk.
