i have tried couple jap sushi in DT. I think Sushi Zero One (on Pender) is quite good. Not expensive and pretty good quality. They have not much seat, so mainly for take out. i like their Don. http://www.sushizeroone.com/
ic..how about Japa Dog on Robson? Any comments?
I'm right next to BC Place, I sometimes go to Subway near library, or VCC for lunch, if I don't pack anything from home.
