The architecture in New Zealand, at least the rural parts, remind me of that in Australia, meaning that it is more American than British. Along National Route 1 down to Wellington, I came across this diner, which advertized itself as an "American Diner". It had a large US flag waving out front and the interior was tastefully designed in classic Americana. Even though I was still full from my huge breakfast, I had me a very tasty milkshake.
Have a look at the place...
Sweet, sweet American cultural imperialism.
The menu had many American sounding items.
