I think that choosing a single food as your favorite food is not something simple since there is a great variety of flavors and textures, and personally I really like tempura foods.
So without further ado, I could say that Sushi (California Rolls) is my favorite food.
Although the "California Rolls" Sushi set is not typical of Japanese culture, since they contain cream cheese and American ingredients (Mayo spicy, cheddar, etc. which I hate in sushi), I choose the middle ground between Japanese and American, keeping the original flavor of the Japanese ingredients, but adding the cream cheese and American style tempura.
My favorite in this category is the shrimp breading with chives and teriyaki sauce (although in Japanese culture teriyaki sauce can only be used for eel sushi, I really like its flavor and prefer it since I don't like soy sauce).
I am aware that this is not very good for my health or my physical condition, however I usually eat this once a month or so, besides, how bad can tempura sushi be compared to a plastic hamburger from McDonald's? Hahaha.
