There are not so good fast-foods in my country so I like going to McDonald's. Burger King is fine but I prefer eating on McDonald's. I never heard about In&Out (there isn't one where I live) but it seems better than the other fast-foods.
Wow. Lots of people from Cali. I've only been to In-N-Out Burger four times and it is delicious. Too bad it isn't coming back to Maryland any time soon.
I don't think Pizza Hut or Hell Pizza can be considered fast-food restaurants though. It's that "under 40-seconds" thing that classifies it as such.
I mostly go to McDonald's and order the 1/3lb angus baconcheeseburger, medium fries, and a large sweet tea. That's my lunch-of-choice when I choose to eat after college.
