OHR is a very homey restaurant that serves very homey food. In western culture, fine dining is often associated with high quality food. In Asia, this is not always the case. A lot of times the best food is found in a hole in the wall. Is OHR such a place? Probably not. But it remains the only Okonomiyaki place in Toronto (that i know of). The staff are Japanese too. So if you haven't tried Okonomiyaki before and don't want to fly all the way to Japan for it, this is pretty much the only place to do it.
For about $7-8, you get a pancake, okonomiyaki sauce, and mayo. You can choose stuffings from meat to seafood. You can add bonito flakes at extra cost. The ones I've tried in Japan are definitely better. But this one is not bad.
If for some reason you come here and don't get Okonomiyaki here, they also sell stuff like teriyaki. I recommend sticking with the Okonomiyaki because it's their specialty.
