If you want food i would recommend The House of Blues... or Rainforest Cafe. If you have a House of Blues near you then go to Rainforest. Its a very very cool err wild place to shop and eat
Well seeing how you are from the UK i would say to eat go to the Rainforest... i think there are a few House of Blues places in the UK... so go different.
To shop... this is tuff... i think you would have a great timejust walking to the end and back and just stop along the way at things that spark your interest. Although i suggest the World of Disney store. You cant miss it. Its the giant one in the middle.
