Located on the very outskirts of Toronto and in Scarborough, decent Japanese food can actually be found. It was a few blocks from the hotel I stayed at when I was in Canada for the night. - It was quite depressing when this was the last night being in Canada and I was not able to enjoy some delicious Toronto food, however, it all worked out in the end.
If you are a big takoyaki lover like me, you must try the Osaka Fried Rice. Every bite you take will taste like heaven on takoyaki land. $9 CAD for this is the best buck of your money and you will definitely not be missing out on anything.
Another great deal was the Salmon & Ikura Gohan ($17 CAD). If you are a salmon and roe lover, this is a must have. The roe was not salty whatsoever. The perfect amount of pop when you burst the teeny roe.
If you love baked oyster, definitely get the oyster mayo with cheese. Quite pricey for an oyster for $8 CAD, but it is hard to find places that bake its oyster with cheese.
