I like things that are low-key and stable... I would much rather stay home to read a book rather than go out to a crazy late-night party.
Or perhaps be on that couch cuddling with someone AND reading a book?
Books: Romance of the Three Kingdoms, history books and historical fiction
Music: J-pop and anime/gaming music mostly
Food: Anything spicy really does the number for me: Mexican anything, Indian curry/masala, spicy BBQ, etc. Also Japanese(sushi and takoyaki!) and Chinese(chow mein!) foods, not to mention Korean BBQ or tofu pot
Cuddles and hugs are deal-makers!
