Guu was the original izakaya restaurant in Toronto coming from Vancouver. I went there at the original location on church and McGill. Lined up for one hour. Food was good but very noisy and the long line deterred me from going back.
Then it changed name to kinka. I went there with some friends for dinner on a weeknight. There was no line and we set on the patio. I guess izakaya craze has died down in Toronto so no line is good.
Walking past the indoor part of the restaurant, it was still quite noisy but the patio is much nicer. You get your own table and it is not loud. Food was very good. Menu looked like Guu. I heard it is the same people but didn't want to pay licensing fee to keep the name. But no matter it is much nicer to be on the patio. I would go back for that but not so much sitting inside so only summer dining for me there
