Manpuku is a good introduction to Japanese food for those who are new to it.
It's good because the portion sizes are small, and the prices are very affordable.
Also, it's one of the few places where you can get homemade takoyaki, fresh from the grill. (That being said, I'm not a fan of the wet, creamy type of takoyaki. I like mine fully cooked).
So why didn't I give it 5 stars? Because none of the items are exceptionally good. There are too many choices, and as a result, you can find higher quality versions of ramen, udon, tempura elsewhere in downtown Toronto.
But if you want a place where you can find affordable trial sizes of Japanese food, this is the place to go.
