So I went to Niji a little while ago for a lunch, and to make it brief, I was astounded by the amount of food I got. I was sitting at a standard two person table, and my meal alone filled up the entire table!! I swear I'm not a fatty, they just give a lot of food.
Don't expect extraordinary sushi or anything, but they have decent rolls and large bentos that will fill you up for affordable prices.
Be warned! As of when I went a couple weeks ago, there was no air conditioning. And be prepared to fight off a particularly annoying fly (just one!) that I had to deal with my entire meal.
Besides that though, everything is fairly fresh and it's probably one of the better, affordable sushi places in Scarborough.
