I do not know how far out you can book but just call them and English is fine.
I assume the prices are the same but do not be shocked(especially in 10 months) if they are increased.
Ok, here is a bit of a summary.
Panic, Teppanyaki, Roppongi-Overpriced, it is Roppongi and Teppanyaki, both things contribute to that. It is solid, though.
Suzuran- Noodles, Shibuya- Really good, maybe excellent. I cannot imagine there are more than 2 better shops in Tokyo.
Le 6eme, French, Ginza- Good, not great, French, very friendly people(uncommonly so)and spoke English well. 1 star Mich, I believe.
Kyubei-Sushi, Ginza-Consensus seems to be #2 Sushi joint in town. Was very good. Rolls at the end were quite underwhelming though and the miso gave me a week's worth of 3rd degree burns. Some great pieces, some not, simple combos, chef will tweak your order according to your taste.
Roti(Tokyo Midtown, seems to be much the much better location)-American, Roppongi-Large for Japan servings(not large), solid to good food. Service would be better if performed by chimps who spoke no English or Japanese.
Isehiro-Yakitori, Ginza-Great chicken, not much else to say. Perfectly cooked, good tasting stuff, lunch is much cheaper(that is common in Tokyo and most large cities with good food).
Cicada-Spanish/Med, Nishi Azabu-Was ok to good, I was disappointed compared to what I had heard. I would be willing to try again as perhaps my dish selection was not the best.
Aburiya Fudo-Otomesando, Izakaya-Good food, I didn't find it particularly great and I sampled across the menu. Chicken wings are the one thing I would not skip.
McD's is probably a better bet than both.
Overall, Isehiro and Suzuran were the only places I really thought were worth going back to. I was the only Gaijin in pretty much every place, every time I went, except for Roti(my group, only people), Cicada and Panic(Roppongi, always expats, was not my choice, neither was Roti).
Many places are booked or have weddings or are just randomly closed. It is really annoying to say the least. Wanted to go to Kojyu(Ginza), was closed for the week, at least, it seemed.
Eat lunch out(if you care about cost and are on holiday with time during the day).
Anything else? I'll check back sometime.
Sic Masshu is def not in operation, don't waste your time calling or searching for it.
