This is a staple of the Yonge/Eglinton workers who would frequent it in flocks. It was always my first choice when a coworker asked "Where do you wanna go for lunch?".
First off, lunch is cheap. Great variety of bento boxes ranging from sashimi to sushi to bulgogi to tempura to pretty much anything Japanese or Korean (ok, maybe not that much variety). $7-12 will get you a crazy amount of food. The tempura is the best I've ever had -- big, fluffy, and light batter. Very unique, no idea how they prepare it to make it different.
My favorite is the Korean chicken (spicy and sweet chunks of chicken, mainly dark meat) with tempura bento box. Best $9 meal in the area in my opinion.
Only went there for dinner once, which is obviously more expensive, but equally as delicious. Lunch is much better in terms of value. Oh yeah, pick-up at lunch is even cheaper!
