This was my first experience at Guu SakaBar - as always, I rate Japanese restaurants based on my experience living in Japan for 7 years. With that in mind, I found the continual screaming quite annoying as they aren't only yelling greetings to incoming and outgoing patrons but food orders and even small talk. Given the layout of the bar it makes it difficult to talk to other people at your table. For those of you wondering - this amount of yelling NEVER HAPPENS IN JAPAN.
So why 4 stars? On the plus side the staff are all mainly Japanese which gives the food authenticity. Most of the dishes do have a Western Flare to them but they were all very delicious and as close to the real thing as you can expect given that ingredients for purchase in Canada are obviously a bit different in some cases. Further the music/atsmophere of patrons was amazing and definitely a contributing factor as to why there is a continual line at this place.
FInal Recommendation - Definitely check this place out at some point if you haven't been, but it certainly isn't worth waiting an hour in line for.
