i find that guu is great if you're comfortable with sharing food & drinks with other people. every time i went was with a group of 5-6 friends, and it's always a positive experience.
on different occasions, i've tried the following and they are all delicious!
- food: karaage, ebimayo, takoyaki, okonomiyaki, grilled saba, & salmon tataki
i also discovered a couple of drinks that i really like that i was able to share with friends: takara plum wine, you's time yuzu flavoured sake
