Yay, food suggestions! For breakfast foods: brioches, croissants, fruit, yoghurt, and café au lait for the civilised meals, and black pudding, bacon, eggs, fried tomatoes and builder's tea for the more, ah, grunt-worthy ones.

As for lunch/dinner dishes: Borscht (http://en.wikipedia.org/wiki/Borscht) is tasty and looks enough like blood to cause raised eyebrows, maybe. Or hopefulness among the vampire population.

Since so many of our characters are Japanese, a standard Japanese meal of rice, soup, and pickles/vegetable/tofu side dishes would probably be welcome.

Lutefisk (http://en.wikipedia.org/wiki/Lutefisk) is a winter dish, served with bacon, mashed peas, and (sadly) potatoes, and it's very much a love-it-or-be-utterly-horrified-by-it kind of dish.

Other than that... bouillabaisse, bacalao, ratatouille or goulash would all be warming dishes in wintry weather.
