My favourite Japanese restaurant in town, bar none. I love their Katsudon. I love their grill selection. I love eating in, and I often call in for take-away when I'm at work. I love that they have pictures of all the items on their menu to help you figure out what something is if you don't know it. This is VERY helpful in an ethnic restaurant, even if it's a food you are reasonably familiar with.
Do NOT go if you are on a time crunch. I don't think I've seen more than one waitress at a time every time I've gone there. And, their English isn't the best, but they usually take the time to make sure they clarify your order.
I should state, I cannot speak to their sushi selection as it is the one area of their menu I am completely unfamiliar with. Quite frankly, in a town awash with solidly decent (and a couple horrifying) sushi joints, it is nice to find a Japanese restaurant that focuses elsewhere.
