My favorite food, what I can eat anytime day or night, what I eat when I am not feeling well, what I eat when I have nothing else to eat, is ochazuke. Basically rice with tea (or could be broth) poured over. It is a luxury to have this at a nice restaurant and I do this whenever it is offered (not common). It's the perfect end to a meal, or the perfect meal. It's not the healthiest nor the most nutritious of meals. It's basically a vehicle for me to eat umeboshi, another favorite.
