Personally udon gratin was sooooooooooooooooooooooooo good and the bonito flakes were exquisite. The gratin was done so well especially considering how wrong it could have been.
We've also had the duck naban udon, hot bukake, cold bukake udon, mixed tempura, kaikage, tempura soft boiled eggs, and the pork belly mini bowl. All were very good. I enjoy that this place puts out quality food seeming to take consideration of balance of flavors.
