I've been here twice because it's close to Lee's Palace and the other options nearby aren't very appetizing.
It's not that this place is particularly bad, it's just that it's nothing special and I wouldn't go out of my way to visit it. There is no way that this is the 'best sushi in Toronto'. I suppose if you're hammered out of you mind anything tastes amazing. It's cheap considering it's somewhat central location but this is Toronto and there are a bazillion Japanese restaurants many of which are better.
One good thing is that unlike some other Asian restaurants, they don't seem to give you a big fuss when splitting the bill. Other restaurants just look at you with that a blank stare but New Gen actually suggests it.
