Been there twice -- regretted it both times. The first time I had udon, which was simply bad. I have been to Japan twice and and eat noodles from reputable Japanese restaurants frequently. This barely qualified as "Japanese" food.
The second time, I ordered only appetizers, thinking they could not mess those up. I was wrong. Even the miso soup was bad -- seaweed was not properly re-hydrated, the whole thing was way too salty, and they served it with a spoon. The tofu salad consisted of iceberg lettuce, a slice of tomato, and 4 slabs of slimy tofu with a crappy carrot ginger sauce on the side. It looked and tasted bad. To top it off, the spicy tuna roll was simply inedible. It tasted like a sponge. If it were not bad enough already, the tea was lukewarm. I will not make a mistake in going here again.
