Had pretty high expectations as well but it was only alright.
Suggest they should have a uni cream one, makes it more special. I would suggest the tsuki dipping udon which is kinda chilled but is the correct chewy-ness. The price was really reasonable but sorry just didn't find it that special.
Salmon cream was alright but uni would have been better imo. I remember the udon place in Hawaii being really good and left me with a craving to come back. This place just didn't seem to have that.
