This is a food stall inside a giant Asian supermarket. Go there if you want to try some Japanese street food like takoyaki and different types of okonomiyaki aka "Japanese pancake" or "Japanese Pizza" (YES - they have Hiroshimayaki as well as Osaka-style). Don't go there if you are looking for California rolls or spicy tuna rolls.
Hiroshimayaki - I wouldn't say they are close to the best in Hiroshima, but hey, it's hard enough to find any (this is the only place in GTA that I have been to that cooks Hiroshima style okonomiyaki) and what's offered here is pretty good! Simple toppings - pork or shrimp or squid or a mixture of all three. When the store was first opened, the owner/chef used to automatically douse his okonomiyaki with the sauce and Japanese mayo before sprinkling on katsuobushi(bonito flake) and aonori(dried seaweed). Now, he asks his customers if they want mayo (Hello?! this is not the time to be health conscience, beside Japanese mayo is not Kraft). I wonder if it's because too many customers ask him to cut the mayo.
Takoyaki -- I think they have the best in GTA. An order comes with 6 or 8.
You can also get osaka-style okonomiyaki or modanyaki (osaka-style plus yakisoba), a few noodles (udon and ramen) which I'd never bothered trying.
