+.5 for service
I felt there was something missing in my visit. I really wanted to love this restaurant because it's something unique and I really love udon noodles in general. However I simply can't give this place 4 stars.
I wanted something different from udon noodle soup as that is very common everywhere. I decided to have the tsuke udon with mushroom soup in the lunch menu. I expected the mushroom soup to be boiling hot, but unfortunately it was just between lukewarm and bearable hot. This made the first half of the udon (which by the way I really liked) very delicious, but the second half kinda tough to eat due to the fact the udon was too chewy from the cool to lukewarm soup. I kinda wished the soup bowl was a little bigger, as that would really help with pulling more noodles into the bowl of soup.
Service was great though, and the chef seems to know half the customers when I was there. They also sell the handmade udon used in the udon meals for customers to boil at home, so if you enjoy the udon here and want some to take home, that is entirely possible.
In terms of me coming back though? Meh, given the cost it would have to be some sort of event...
