Not as busy as the Guu Izakaya on Church. Even since this location opened, I have never gone back to the other Guu. There are so many Izakaya's now in Toronto but Guu has always been the one I go back to because it never disappoints me.
They have a good variety of dishes with the special menu updated daily. The price is reasonable but I would like to see more variety in the dessert menu though :)
