This is a great place to go if you're looking for somewhere to hang out that's fun, relaxed, loud, with great food.
Like many in Vancouver I'm a big fan of Japanese cuisine, despite being allergic to seafood. There's typically a great variety at restaurants such as Hapa, Zakkushi, or Ebisu and Guu is absolutely no different. We ordered the two udon dishes, the deep fried brie, grilled beef ribs, and the raw tuna plate. Every dish was unique (especially the deep fried brie, never had that before. Highly recommended) and delicious.
Service was typical for a lot of high energy Japanese restaurants in Vancouver such as Gyoza King or Zakkushi on Denman, lots of shouting, smiles, broken English, and quick service. The place was packed but we were quickly seated at the bar, our order was taken promptly and our food and drinks came surprisingly fast.
Layout of the place is excellent, it's two levels with most of the seats on the upper level and the main level being the bar and kitchen. Very open design, great use of lighting, music, and design to come together for a welcoming and casual environment.
I would definitely come back here, it's a great place to spend some time with friends and have some drinks, eat some delicious food.
