I may be biased because I'm a northern hick and not much of a culinarist (food is a mean of filling your stomach), but the best food I've ever eaten was sauerkraut and bratwurst in an old Bavarian beer hall. Different kinds of real, meaty sausages (not like that industrial crap we have here), different kinds of brötchen, sauerkraut, weissbier..
Italian foods are classics. Traditional Slovenian food was also very nice.
