Went for a Sunday lunch.
The food is very mediocre. With so many all you can eat sushi places at similar prices, one should expect decent quality food.
Kanda is the equivalent to the "fast food" of all you can eat sushi. The rolls are pre-made, so they leave the kitchen at record speed. Our sushi roll order came in under 3 minutes. The sushi is somewhat hard and the fried roll is not even remotely fresh.
Likewise, the other sides are rather bland. The general tao chicken was decent, but the tampura batter had almost no flavour and the dumplings were tasteless.
Look somewhere else for a sushi lunch. There are plenty of good places to go to, where the food is made to order, and the service is still great.
