Many have commented the place was hard to find, and I understood why once I got to the neighborhood where the restaurant was located. Google Map or whatever GPS application you use could get you as far as to the block where the restaurant is located, but the entrance was actually hidden in the narrow side alley next to the building. I am pretty sure I wasn't the only one walking into that art gallery at the front, thinking the entrance was somewhere inside. As a public service, you can see the picture below for the way to the entrance door (just follow the red arrow)
I asked the hotel concierge to make the reservation for me about a month ago just as I finalized my itinerary and a day later, they came back with my preferred timeslot confirmed. I arrived at the restaurant at noon, just as Chef Takao Ishiyama and the team just got ready to welcome their customers. Most of the 8 seats around the L-Shaped wooden counter were soon filled with customers - half of them foreigners and half of them locals. The restaurant was relatively new - opened in 2012 and took up the space of what used to be Sushi Iwa, which has moved a few blocks down then.
I enjoyed the lunch very much and thought it's more than reasonably-priced for what I was served - both in terms of quality and quantity. I had a glimpse of what the omakase meal looked like when Chef Ishiyama-san served to the couple customers next to me, and a few pieces looked very impressive. It did make me wonder for a second maybe I should have ordered that instead. Would love to be back some time in the future, for lunch or dinner.
