First thing first - food was good as confirmed by many of the reviewers before me. I especially enjoyed the 3000+ yen unagi don which allows you to try out unagi chazuke. Although not explicitly stated, you may also add on a chawanmushi and salad...to this don, to make it a set.
Service was also good. As others have also mentioned, the queue is exceedingly long during lunch time. We had great anticipation for the food after the long wait and the food met our standards. I would have easily given this restaurant about 4-5 stars if not for an incident towards the end that completely ruined the experience for me.
After I finished my food, I wanted to use the washroom. From my seat, I saw a male washroom sign located outdoors of the restaurant so like most human beings would (or maybe I'm just a presumptuous pleb), I assumed that is the washroom. BIG MISTAKE. Yes that it is a washroom alright, but not one that the public can use apparently? When a waitress bumped into me in the corridor, heading from the direction of that particular washroom, she glared at me and shouted "NO NO NO" without any explanations of some sorts. Then she slammed the door that separates the washroom to the eating area. (Why open the door to begin with if the public is not allowed to enter? Why aren't there signs that say 'use another washroom' instead?)
Well honestly, I admit it is my mistake if I accidentally trespassed that sacred toilet but I do think it is exceedingly rude of that waitress to shout at me and then, slam a door on my face without explaining why I should not be using that toilet. Until now, I'm not even sure what is going on because there weren't any explanations given. If I did use the wrong washroom then I apologise. Nevertheless, that was an appalling experience (relative to not just Japanese service standards but also, in every other restaurant) given that I was not aware that there was another washroom.
TLDR: Good food, especially the unagi chazuke. It is slightly on the pricier end but the ambience and food met the price point. However, I'm confused on how to rate the service. On one hand, most staff were polite and helpful except for that one bad experience. *Do note that there is one toilet by the entrance which I failed to notice*
