Street food, though typically fast, merits its own category. Fast food in the non-outdoors sense? I'm not sure if any country has the best. The US has a large variety, though less so where I usually haunt (the Northeast). Actually, to be fair, there's not as many US-based chains in NYC as say, oh, many other regions in the states where roadways prevail, but then there are entries such as Korean frozen yoghurteries, fried chicken nooks, a Jollibee in Queens(Filipino), and dare I say the bodegas?

Japan has MOS Burger, which is a favorite standard-issue fast food joint, ramen huts, Matsuya (another choice entry), the Korean Lotteria, beef bowls, and curry houses, as well as places like Original Bento, which has a bunch of choices as well as side dishes. Where am I going with this? I'm not sure, but I'd be just as pleased to walk into a Sainsburys to get a buttered sandwich or a set meal with nuegado at a Mister Donut in El Salvador.

Perhaps my better response is: I don't ever crave fast food in the states, in China, restaurants usually stir-fry up eggplant with long beans in two minutes, and in Japan, I'll eat anywhere. Everywhere else (and including China), street food comes first, then a restaurant.

interesting that the OP didn't even mention the fastfood #1 in many european countries - doner kebap. I can't imagine Germany without it :)

It's all good
 

Mexico - Tacos al Pastor
Singapore - like the street
Everywhere - Big mac (at least once a quarter)
Paris - Baquette with brie/beurre
Cincinnati - 5 way
Philly - Steak, whiz wid

I envy you in a way. I absolutely love the stuff. I limit myself to an average of once a week for health's sake (usually my local independent fast food burger joint), and that takes an enormous amount of will power.

In Argentina...

Flying fish sandwiches at Oistins Fish Fry in Barbados....

Chicago has some unique and yummy fast food.

Well sushi would have actually been the first thing I thought of, for Japan anyway. Is this a new phenomenon? I was in Hong Kong in 1995 and Tokyo and Okinawa a few years later. I don't remember seeing the fast food everywhere, but then again I wasn't looking.

Yes - I think my small town has 5 of them, and the quality varies drastically. I did think of something local I like, and that is the baguette sandwiches I get across the border in places like Cora. Just something about that bread.

Western fast food seems to be extremely popular in at least some parts of the Middle East. I was somewhat surprised to see KFC all over the place in Cairo.

For me, Germany means pommes mit mayo, after a night out. Mmmmmmm!

My own favorite German fast food is that old traditional German specialty, Döner Kebab. ;)

Fresh cut shawarma warp at any arabic countries for less than a dollar can't be beat and usually comes with bottle of coke.

Anyone who says London, or even the UK for that matter, has terrible food is living in the past

That's true.

Even the pub menu has changed over the years.

Los Angeles, Tito's Tacos

While SE Asia (Penang, Singapore, KL, Bangkok, HK and Saigon) is probably on top for taste and quality, I was very impressed with Istanbul's abundant selection, as well. The USA lags far far behind, IMHO. Perhaps the USA leads in junk food?

Definitely true. When I was in London in the mid-80's there were those crappy Wimpy's everywhere. It looks like the chain lives on in a few places. Hopefully they've joined the modern world.

That is exactly the term I should have used in the first place. Is there consensus that the USA is the junk food capital of the world?
