Guu is has a fun and LOUD atmosphere!
It is a great place to go with friends. Sharing dishes and getting a taste of their many wonderful dishes makes for a great dining experience.
I've loved everything I've tried here except for the "SABA" (grilled mackerel). The kinoko bimibap is great! Definitely give it a try.
After ordering a few dishes per person (they are small sharing plates) you're looking at around 25-30 per person (including tip, but excluding alcohol).
