Dashichazuke (Shin-Maru Building B1) This is the only place I eat Ochazuke and is a place that I would gravitate towards almost every weekend. For 800-yen you get a bowl of rice topped with freshly-prepared ingredients such as chicken or fish, a seasonal side dish (like stewed pumpkin in Autumn), some pickles, and a little teapot full of the most delicious broth you'll have ever put in your mouth. Pour the broth on the rice and shove the hot, soupy rice into your gaping maw. For me, this is one of my ultimate comfort foods.

There's also an awesome bakery diagonally opposite.
