Don't ever order one in Perth, West Australia

I'm surprised. I would have thought that McDonald's strived to taste the same everywhere. However, I well remember getting a hamburger in Sydney (not at a McDonald's). For one thing, they asked if I wanted "salad" on it. I figured that was a quaint Aussie expression for lettuce, onion and tomato. Nope. I ended up with beets and carrots on my burger. And there was definitely something up with the beef. I couldn't figure it out, but it tasted like no beef I have ever had anywhere else. Not good.

From what I understand, McD's goes out of it's way to adapt to local tastes. In most countries the beef is local, and are different menu items for different countries. Even in the US, there are some regional differences; Maine sometimes has lobster rolls and the Southern chicken sandwich is not available in many states.
