I can't recommend Waraji enough - it has been the best overall sushi experience I have had to date. (Including Raleigh, Philadelphia, San Franciso and Los Angeles) The combination of fresh food, friendly and helpful chefs and a solid selection of food (including non-sushi) can't be beat.
My only 'warning'? Service can be a little slow when it's packed, especially on the weekends. Go early or go during the week and you shouldn't have any problems getting seated quickly.
(Oh and make sure you try the seared yellowtail.)
