It's a hip place to go in Toronto, and great atmosphere!!! The food, however, I found most of them are tend to be too sweet. Sweetness itself is not a problem in general, and we all love candy, don't we?! But if the food only has sweet flavor in it, that means at the same time it is lacking the actual true flavor from the food. At the end, I'm not not looking for fast-food type meal in an Izakaya.
In short, if you are looking for great atmosphere, Guu is the number one choice!
