Came here with a group of 5, no reservations and only waited for 10 mins on a Friday night during TIFF weekend. So that was pretty awesome.
I felt that service could've been a bit better as every table looked like they've been waiting to be serviced for a while. Although they were under staffed they still accommodated to my needs of ordering sake bombs (a pitcher of sapporo+sake), I guess it's not a common order since the waiter didn't know what I was asking for so I had to explain it to them.
Here's a little 411 on sake bomb
Beer+sake= sake bomb (Asian style of a jagger bomb) fill the beer Mug halfway, make sure the sake cup is filled up and slightly held up by the chopsticks. I think there might be a chant before you slam the table but wishing your friend happy birthday is good enough and at the same time everyone slams the table so that the shot drops in like a bomb ... Literally a mess so make sure you have tons of napkins. Important part of this is that everyone chugs it to the last drop!! (please drink responsibly )
Food was impeccable and different. I loved the presentation of the food but the portions of it makes me want to cry. Prepare to order two of everything or go to McDonalds after :p
Izakaya is tapas style so don't expect to get full off of it. Atmosphere is more upscale than Guu and not as loud and live. I thought the Japanese games on the wall were cool but definitely ruined the feel of a warm lightly dimmed venue with its colorful flashing lights.
