Some things are the same anywhere you go. And not.

Here are the chains that I've seen in NZ as well as the US:

• McDonalds
• Starbucks
• KFC
• Burger King
• Wendy's
• Kmart
• Woolworth's
• Jeep and Ford dealerships

Here are some notable differences from the US:

• McDonald's is colloquially called Macca's.  Kiwis love to use diminutives.
• Fast food is more expensive (maybe by 25%?) than in the States, and the fries/drinks in the combos are smaller.
  
• KFC emphasizes its 'special marinade', not its 'eleven herbs and spices'
• There's a weirdly sploshy commercial for a fruit drink at KFC
• There are some different items on the menus... the BLT at Macca's (and the bacon appears to be more like Canadian bacon than the American strips), the Mayo Burger at BK...
• I remember Woolworth's being sort of a drugstore when I was a kid.  You could buy fabric there, I think.  Woolworth's is a grocery store here.
• A Jeep costs $80,000.
