Indian food is yummy. I'm all for more "adventurous" choices in Disney. I can't stand junk/fast food, and there's already so many places to grab a burger or something.
That said, India would be nice. Buuuuut if it's what I would personally love to see...
South Korea (Etude House store please!), Sweden, Finland, Denmark (What can I say, I adore [Fenno]Scandinavia, and the pastries are diviiiine.), maybe Scotland and Ireland but they do already have 'United Kingdom'-not just England.
