For me, European, Mainly Italian. 

A (very) close second is Latin American. Every country has similar food, with a bit of differences for each. 

You are. That's true for pretty much every major city in the world. London and Tokyo particularly, to name one each from Europe and Asia.

I love my pizza, so I had to go with north america.

Your talking about two of the largest cities in the world.

I'm talking about Columbus, Ohio. Of course, you can get every major type of food in the largest cities in the world. But what I'm talking about is getting a good diversity of food in a town that is much smaller. My home town (13,000 people) has Italian, German, Chinese, Japanese, Mexican, and a few others. Call me crazy, but I doubt you can find that kind of food in every small town in Japan or England. Or maybe I'm wrong.

Same for my town here in southern cali. Small town but every kind of food you can think of. A lot is pretty authentic with it being made by immigrants from what ever country the food is from.

sushi> the world. now bow down to kojima the ultimate sushi maker!

Asian for me, especially Chinese, Japanese, Thai.

Though I love the sweets/desserts of Western Europe and the Middle East a lot more than East Asian ones.

NORTH AMERICA!!!!!!!!!!

They made Mcdonalds

North America.  Pizza, apple pie, hamburgers and franks, good 'ole Southern Comfort food, "Soul food", Louisiana Cajun/Creole cuisine, Tex Mex.

Oh and Peanut Butter, Coke, milkshakes, gum, packaged breakfast cereal, and McDonalds. lol YOU'RE WELCOME

Asia. Thai, Indian, Japanese, Chinese, Korean, Vietnamese, Malaysian, Lebanese, Syrian and so many more other styles of dishes. We have restaraunts for all these styles in Melbourne, but when I went to Malaysia, Japan and China, I was blown away by how good the food was. China was very hit and miss, but Japan was amazing. Okinomiyaki is probably the greatest dish I've ever had and I haven't been able to find someone in Australia that makes it as good as a random alley way diner in Osaka. Everything is different and high in quality. McDonalds also tastes amazing in  Japan for some reason, but in Australia it tastes like complete shit.

People also over look Middle Eastern food way to much, I eat plenty of it here in Australia, but when I went to Lebanon, the restaraunts had lakes going through them with swans swimming along, the food was homegrown and amazing. The atmosphere when your eating in Lebanon is weird, it's like every meal is an event, everything is fresh and great care is taken in the cooking. The sweets are also incredible, people only recognise balaclava, but the sheer variety they have can be pretty astounding, it's also crazy how much effort they actually put into the dishes, I've tried making a few and I've failed every time. Out of the countries I've traveled to, Lebanon and Japan rank the highest, Canada is probably the lowest.
