Guu was the most upscale of Japanese restaurants I visited during my short visit to Toronto. I did go for late afternoon lunch on a weekday so it wasn't loud at all and the energy of the kitchen staff and servers was warm and welcoming. The hamburger steak was the best I had. It was thick, nicely textured, juicy, and bathing in a succulent tomato-based sauce. I'm sure it would be top class it was a hamburger. With the "tapas/small plates" label in mind, I thought the portion was very generous. Total $14.46 tax included.
