Decent sushi near Union Square
I'm hoping to find a place within one or two blocks from Post at Mason that has decent sushi. Doesn't have to be out of this world, just a place decent for lunch take away.
I love Sakana on Post and Taylor but it isn't flashy. Generally has real Japanese people eating there. They always have lots of interesting fish and pretty good apps.
Also, I like Ryoko's right next store. Cool atmosphere and great karaage (Japanese fried chicken) and also has other great izikaya style food (Japanese bar food).
