Tonkatsu Wakou Tokyo Station Ichibangai

My brother suggested 和幸 Wakou for tonkatsu. The last time even though the food was amazing (so was the service, read my review on Ginza Bairin to learn the whole story), he did not get to properly enjoyed his food since our mom was unwell and throwing tantrum.
He had eaten at Wakou 和幸 before when he travelled to Tokyo for work. Work was just next to Tokyo Station, a high rise office building which I still did not know which one. Even though he was hesitant to suggest a tonkatsu place (since our dear mom was complaining we had been eating too much fried food), I told him just planned accordingly and we would order non fried items to appease our mom. We tried to beat the lunch crowd and arrived at the restaurant slightly before 11.30am. As expected, our mom cried foul that we chose another «fried food place».
I ordered the 2 prawns and 2 pork tenderloin. Food was definitely excellent especially the prawns were definitely a hit. They were so crispy. What so special here was the miso soup that came with the set had some super tiny clams in them. The flavor was slightly different from the usual miso soup and had a seafood flavor in it.
Unlike Ginza Bairin, the atmosphere was cold even though the server who took our order was polite. I could not find complete fault in the service, ambience or food. There is just something missing here, maybe a lack of warmth in this place which I had been experiencing everywhere else in Tokyo. I would still come back for the food though and definitely ordering the prawns.
