There's a small restaurant near my apartment that has amazing tonkatsu and it's extremely filling, especially if you order a "set." In Japan, if you order your meal as a set, you get a little more for your money. In my case, I paid an extra 315 yen for a bowl of rice (with radish leaves in it) and a parfait. Cabbage and soup also comes with your meal for free.
I love the set concept because you only pay a little more for a whole lot more food.
