Okinomi House on Charles Street, Toronto
I don't see anything on this restaurant on any board so I think I should say something...it is the only place in Toronto where you can get this famously good Japanese meal; I think it is fast food in Japan. I have tried various dishes at this restaurant but the deluxe seafood okinomiyaki is my favourite. The place is always pretty busy; I am surprised I can't find any comments here.
I actually prefer the style of okonomiyaki from Koyoi around the corner. I've found Okonomi House to be really greasy, or at least much greasier than it needs to be. You can find slightly different versions in izakayas (or sometimes just regular McSushi joints) all around the city.
It's super cheap and a reasonable facsimile of okonomiyaki, but the one at Koyoi (as noted below), is much better. I've also found Koyoi (despite being Korean-owned, Japanese-staffed) to do a better rendition of the dishes also served at Guu (eg: kara-age, etc.).
Koyoi, however, is much more expensive than Okonomi House.

The one at T&T Middlefield was better imo. The Okonomi house's are too thin I thought, and they put waaaay to much sauce. Idk just generally not enjoyable to me.
This place gets a lot of love/hate. Either you like their particular variation on okonomiyaki or you don't. I don't have much to compare it to, but I find it to be satisfying as a comfort-food now and then, even though I agree it is a bit heavy and saucy for regular consumption. I also love the 1970's truck stop feel of the restaurant, the friendly staff, and the cheap prices. I wish Toronto had more quirky little spots like this.
