AVOID the teriyaki chicken! It's really, really bad. Driest I've ever had, and I never understood my colleagues loving it so much.
Whenever I would come here for lunch I would stick to the panko fish or pork katsu, plus a mochi for dessert. The inari sushi is also good. Their rice is fine, but the nickel and dining up-charge for brown rice or spicier food just makes them look cheap.
Note that it does get crowded during the lunch rush, and the better (non-teriyaki chicken) items take longer to cook.
