I went to Guu recently as part of a group. Guu is a restaurant unlike any other Asian restaurant I have been to . They have a quaint dimly lit space with wooden seats. The servers welcome you with a loud welcome and if your table orders sake bombs be prepared to hear chants of ' Sake... Bomb Sake..... Bomb.. We had a bunch of well cooked items such as a Miso Chanko nabe hot pot , saba sushi, beef skewers , and sashimis such as tuna, mackarel,hotate, octopus and salmon . The experience was excellent and unforgettabl. I liked the Izakaya concept since the table orders a bunch of dishes and you try a little bit of each. I will be back again for some more Guu because Guu is Guud!!!
My word of advice is not take non adventurous people for such occasions as it hampers the experience for the adventurous. Be strategic in what your order. Luckily the group I was with was adventurous so we were able to enjoy what we did .
