I just had lunch here and have rarely been so impressed by a restaurant's service. We actually arrived 20 minutes before they opened, but the man at the in front insisted on serving us anyway.
During the meal ($10 all-you-can-eat!), we were continually asked how everything was. We received our food quite fast and were satisfied with everything. They even include dim sum on the menu, which was a nice surprise.
From our seat on the patio we could see the greeters handing out free sushi samples to passers-by. It's incredible the effort they put into this restaurant.
If you want good, reasonably-priced sushi with what I'd say is exceptional service, you should definitely give this place a try.
