I've been to Guu out in Vancouver and here and have yet to be disappointed. The okonomoyaki is amazing as well as the sable, any of the carpaccio's are also delicious.
You are greeted as well as sent off in Japanese! I suggest going in a small group as you are seated quickly. Their patio is a great place to have dinner if the weather is nice.
Most dishes are small and you can share them, but only if you feel to! Pretty much nothing has disappointed. I suggest you go and go soon!!!!
