I will be traveling to Tokyo for business toward the end of February. I will be spending 3 days and 2 nights in Tokyo, but the latter 2 days are going to be packed with meetings so I am taking the red-eye in from Singapore (I live in Manhattan but will be in Singapore before Tokyo for work) on my first day there to have a full day to walk around and eat. Japanese food is my favorite cuisine in Manhattan, and I frequent all the top sushi spots in New York (15 East, Ichimura, Tanoshi) and love all forms of Japanese cuisine (Katsuhama, Ippudo, Yakiniku Futago, Takashi are all favorites as well).
I know Tokyo has unlimited options, but given my limited time there, I was thinking of trying a top Sushi-ya for lunch and a Kaiseki place for dinner. I would be dining alone for both meals. I land at 7:30am on a Wednesday morning and will be staying at the Peninsula Hotel near the Imperial Palace. I just contacted the hotel concierge to try to secure lunch at either Mizutani, Saito, Sawada or Jiro for lunch and Ryugin for dinner, but I know all of these places are extremely hard to get a spot at so I'm trying to find other alternatives that CHs love. Price is not an issue, and I really would like to experience food that would not be available anywhere in the US. Luxeat has a list of the top 50 sushi bars based on tabelog, but I'm curious to hear from CHs who have dined at them and have favorites to recommend. I'm also open to trying a great yakiniku or tempura place for dinner but I feel like the level of differentiation versus what we have in NYC (Matsui/Takashi) may not be as large as what I can hope to find with sushi and kaiseki meals. Lastly, I'm also looking for a casual quick meal after I land and leave my bags at the hotel, which would be around 10am, or a bite in between lunch and dinner if I don't feel too stuffed.
So in summary, please let me know if you have recommendations for:
1) A top-notch sushi place besides those already on my list (and not Yoshitake, as I've tried Sushi Shikon in HK)
2) A highly rated kaiseki place besides Ryugin
3) Ideas for a casual breakfast meal and a snack/bite between lunch and dinner
