Toss up for me with Japan and China. I essentially grew up on Japanese cuisine due to our upstairs neighbors always watching us while my mother was in school and my dad was working on base. Now I eat a ton of Chinese food because Japanese cuisine isn't that common yet although we now have a Kyoto's Express in my town, woo hoo.
I've been enjoying Indian cuisine a lot lately. Samosas, different breads (naan is yummy) and proper curries. Boy do they make 'em hot! I was going to say Italian overall though but roast dinner and fish and chips is hard to argue with. Sunday roast is my absolute favourite. Giant yorkshire pud, chicken, roast tatas, peas, sausages and stuffing smothered in gravy. That alone is worth 200pts. I'll go with the infamous English cuisine too.
