Came in for lunch today... yup, the reviews were right. Lunchtime all you can eat sushi, made to order mind you, is legit!
You can order as much as you want, they only ask for you to be able to finish what you order. They will charge for extra. No problem for me, soup and a couple of rolls will work just fine.
The wait staff was very nice and attentive. Overall, great experience for a sushi joint. I was a little bummed that sashimi isn't on the lunch menu, this is probably because there isn't any rice to fill you up.
Do it for lunch, and yes, show early because they get busy at 12:00.
